Yesterday, 27-year-old Scottie Scheffler claimed his second Masters victory in three years, cementing his place among the golfing elite. On a course that has challenged even the greatest players, Scheffler finished Sunday by once again donning the iconic green jacket. I recall writing about his first triumph at Augusta National back in 2025, where his wrist bore the glint of steel and gold beneath the green sleeve of his new blazer. That year, his replica watch of choice was the “Root Beer” Rolex GMT-Master II in Everose Rolesor, a stunning two-tone mix of steel and rose gold. It was a bold and unconventional pick for a first-time champion. 

But after yesterday’s victory, as Scheffler stepped up to receive his second green jacket, his watch selection hinted at a new level of confidence – one that undoubtedly contributed to his success. As an official Rolex testimonee, Scheffler has the freedom to wear any Rolex model he chooses. While it’s common to see athletes sporting watches from the current collection, Scheffler made a striking, and much greener, decision.

As he slid his left arm into the sleeve of the Master’s symbolic green jacket, the setting sun caught the emerald hue of his copy Rolex Submariner’s dial. This wasn’t the modern green-bezel “Kermit” Submariner (often referred to as the “Starbucks”), which has a black dial. Instead, Scheffler was wearing the now-discontinued Rolex “Hulk” Submariner Ref. 116610LV, distinguished by both its green bezel and green sunray dial, housed in a 40mm case. (For more background on this reference, you can check out my earlier article here.) Rolex discontinued the “Hulk” in 2020 to introduce a new series of 41mm Submariners, including a revamped green bezel model with a black dial, which remains in production today. 

This makes the “Hulk” a particularly interesting choice, given that it’s been out of production for four years. Scheffler could have easily opted for the more current 126610LV “Starbucks” Submariner, but something drew him to the all-green dial of the “Hulk.” Having been a pro since 2018, perhaps this replica Rolex Submariner holds personal significance for him. But more than that, it seems he approached this year’s tournament with a different mindset and a new swagger. It’s almost as if he knew that if he were to claim the green jacket a second time, his watch had to match perfectly.

One of the most appealing aspects of Rolex watches is their enduring design. Whether it’s a sports watch like the Submariner or a dress watch like the Day-Date, many Rolex models have maintained their classic look since their inception. Despite their consistent design philosophy, replica Rolex has made subtle improvements over the years. The brand is known for its careful updates, which preserve the iconic appearance while incorporating gradual technological advancements. 

A key way to identify important features of a Rolex watch is through its reference number. Let’s explore the differences between 4, 5, and 6-digit reference numbers on Rolex watches and what they reveal about each model.

Decoding Rolex Reference Numbers
Rolex reference numbers, while seemingly random at first, provide a wealth of information about a watch’s production era, model type, bezel style, appearance, and even the materials used for its case and bracelet. Here’s a quick guide to understanding these numbers:

First two to four digits: Indicate the model type or family, such as the Datejust, Daytona, or Yacht-Master.
Second-to-last digit: Denotes the bezel type, such as smooth, rotating, or fluted.
Final digit: Specifies the material of the replica watch, like steel or Everose gold.
Letters: Describe gems, colors, and other elements.
For a comprehensive guide, refer to our “Rolex Reference Numbers Explained.”

Evolution of Rolex Reference Numbers
Over time, Rolex has used different lengths of reference numbers, ranging from 4 to 6 digits. These numbers are engraved between the lugs on the 12 o’clock side of the case. Here’s how they evolved:

Production Periods
The number of digits in a Rolex reference number can indicate the production era. Rolex gradually added digits to its reference number system for each model, so there isn’t a single year when all watches transitioned to a longer reference number.

Generally, wholesale Rolex watches with four-digit reference numbers were produced before the late 1980s and are considered vintage. The brand began using five-digit numbers in the late 1970s and completed the transition by the late 1980s. Whether a five-digit Rolex is vintage or discontinued depends on its age.

In the 2000s, Rolex introduced six-digit reference numbers by prefixing the existing number with a 1 or 2. For example, the Explorer II’s reference number changed from 16570 to 216570, while the core numbering scheme remained consistent.

Rolex Reference Numbers and Letter Codes
In 2005, Rolex introduced the Cerachrom ceramic bezel, which was accompanied by the introduction of six-digit reference numbers and the addition of two or four-letter suffixes. These letters indicate the color of the Cerachrom bezel on a watch.

For instance, the Rolex Kermit ref 16610LV uses “LV” for Lunette Vert, or green bezel, while the Rolex Milgauss ref 116400GV uses “GV” for Glace Verte, or green glass. Models with two-tone ceramic bezels, like the GMT-Master II Batman 116710BLNR, have four-letter codes. “BL” and “NR” stand for “blue” and “noir,” signifying a black and blue ceramic bezel.

Previously, a six-digit reference number indicated that a watch was in current production. However, starting around 2015, Rolex began retiring some six-digit models and replacing them with updated versions, while maintaining the six-digit system.

Luminescent Materials in Rolex Watches
The luminescent material on a clone Rolex dial can also help distinguish between 4, 5, and 6-digit versions. As luminescent materials evolved, different lume types appeared on models with the same reference number.

Radium was used until the early 1960s, tritium until the late 1990s, LumiNova until around 2000, Super-LumiNova until the late 2000s, and Chromalight from 2008 onward. Chromalight was initially used alongside Super-LumiNova until Rolex fully transitioned to its proprietary blue-glowing Chromalight.

A watch using tritium or radium likely has a four or five-digit reference number. Those with Luminova or Super-LumiNova typically have five or six digits, while Chromalight indicates a six-digit reference number.

Crystals and Bezels in Rolex Watches
Rolex has also updated the crystals that protect its dials, moving from acrylic to sapphire crystals. Five-digit references can have either acrylic or sapphire crystals, while all six-digit references feature sapphire.

Rolex eventually replaced aluminum bezels in the Submariner and Sea-Dweller lines with Cerachrom and swapped the steel bezel of the Daytona for a ceramic version. Cerachrom also appears in matte form in the Yacht-Master series.

If your Rolex has a ceramic bezel, it’s a six-digit reference.

Evolution of Rolex Bracelets
Finally, Rolex bracelets have evolved over time. From the iconic Oyster to the elegant Jubilee, Rolex is renowned for its bracelet designs, which have been enhanced for durability and comfort.

Introduced in the late 1930s and patented in 1947, the Oyster bracelet originally had straight lugs but was later fitted with curved “flush-fit” end links for a precise fit.

While the bracelets were well-crafted, the end links were historically the weakest part. These hollow links could rattle over time and had a noticeable seam. In the early 2000s, Rolex addressed this by adding solid end and center links to the Jubilee and Oyster bracelets, reducing potential damage by minimizing openings for dirt.

The Rolex Daytona commands admiration from both casual admirers and dedicated collectors alike, weaving together a tapestry of speed, luxury, and precision. With its roots deeply entrenched in the world of motor racing, this iconic timepiece has evolved through the ages, becoming a symbol of timeless elegance and technological innovation. 

The saga of the replica Rolex Daytona unfolds across two distinct epochs. The first chapter traces the journey of the manual-winding Daytona, epitomized by the legendary “Paul Newman” Daytona, which emerged as a beacon of style and sophistication from 1963 to 1988. This era witnessed the Daytona’s rise to prominence, etching its name in the annals of horological history. Following this heralded era came the advent of self-winding Daytona, marked by the introduction of the esteemed “Zenith” Daytona in 1988, signaling a new chapter in the Daytona’s illustrious legacy.

While vintage Daytona models with their storied pasts have become prized possessions, newer iterations continue to captivate enthusiasts, carrying forward the Daytona’s enduring legacy with aplomb.

1. Rolex Daytona Steel Ceramic Bezel 116500LN

Introduced in 2016, the Rolex Daytona 116500LN stands as a beacon of contemporary design and technological prowess. Featuring a robust black Cerachrom bezel crafted from specialized ceramic, this model ensures longevity and resilience against wear and tear. The stark contrast between the black bezel and the classic white or deep black dial creates a visually striking aesthetic, while the inclusion of the reliable Caliber 4130 movement ensures precision timekeeping, making it a coveted choice for discerning collectors.

2. Rolex Daytona Steel 116520

Debuting in 2000, the Rolex Daytona 116520 marked a significant milestone in the brand’s history as it introduced the Caliber 4130, Rolex’s first in-house chronograph movement. Boasting a versatile design with black or white dials and silver-ring registers, this model seamlessly blends heritage with innovation, embodying Rolex’s commitment to excellence in watchmaking.

3. Rolex Daytona Steel Yellow Gold 116523

The Rolex Daytona 116523 exemplifies the artistry of combining contrasting metals, marrying robust stainless steel with radiant yellow gold. This two-tone masterpiece captures attention with its harmonious blend of resilience and opulence, underscored by its precise movement and impeccable design, making it a statement of style and functionality. 

4. Rolex Daytona Steel Yellow Gold 116503

Drawing inspiration from its predecessor, the 116523, the Rolex Daytona 116503 strikes a balance between tradition and modernity. With refined detailing and improved precision, this model pays homage to the classic while embracing contemporary enhancements, appealing to both purists and modernists alike.

7. Rolex Daytona Everose Gold 116515

Launched in 2011, the fake Rolex Daytona 116515 showcases Rolex’s commitment to innovation and elegance with its Everose gold construction and distinctive black Cerachrom bezel. Combining sportiness with sophistication, this model captures the essence of the Daytona legacy, making it a timeless addition to any collection.

8. Rolex Daytona Zenith Movement 16520

A milestone in Rolex history, the Daytona 16520 introduced the self-winding era with the famed Zenith “El Primero” movement in 1988. Retaining the classic Daytona aesthetics while embracing technological advancements, this model represents a seamless blend of tradition and evolution, earning its place as a cornerstone in the Daytona lineage.

9. Rolex Daytona John Mayer Edition 116508

The Rolex Daytona 116508, affectionately known as the “John Mayer” Daytona, stands out with its captivating green dial and lustrous yellow gold construction. Endorsed by the musician himself, this model marries pop culture with horological excellence, epitomizing style, history, and craftsmanship in a single timepiece.

10. Rolex Platinum Ice Blue Dial Daytona 116506

Crafted from 950 platinum, the replica Rolex Daytona 116506 commemorates the Daytona’s 50th anniversary with unparalleled luxury and exclusivity. Featuring an ice-blue dial and dark Cerachrom bezel, this model exemplifies Rolex’s dedication to pushing boundaries and combining innovation with opulence, making it the epitome of watchmaking artistry.

Currently, the brand offers two new generations replica Rolex Oyster Perpetual Milgauss watches. They feature blue and black dials respectively. Both models have a green sapphire crystal on top. Just like the original model released in 1956, the new specimen has a unique lightning-shaped central seconds hand.
Its case and strap are made of oyster steel (904L), which offers greater corrosion resistance and robustness than other steel alloys. With a diameter of 40 mm, the time-tested Oyster case contains a single mid-case, a screw-down caseback and a winding crown with Twinlock double water-resistance system. It is water-resistant to 100 meters.
Magnetism is one of the main external forces that can adversely affect the precision of a mechanical watch. It can be naturally occurring or generated by some machinery. We often handle equipment with highly magnetic parts, which can cause harm to your watch. To reduce this interference, various measures are applied to antimagnetic watches. One of these components is a miniature Faraday cage. Another method of reducing magnetic flux is to use non-magnetic or paramagnetic materials for movement components.
The internal antimagnetic cage that protects the clone Rolex Milgauss movement is made of a special ferromagnetic alloy. As a Faraday cage, it has an engraving symbolizing the density of magnetic flux. The mechanical movement that beats inside is also antimagnetic. With this innovative construction, the watch achieves an impressive antimagnetic capacity of up to 1,000 gauss.
Available in blue or black, the dial features applied stick hour markers with a highly legible Chromalight display that provides a long-lasting luminous effect. The hour and minute hands also use this proprietary luminescent technology to ensure that the dial is visible even in the absence of light. The lightning-fast central seconds hand is orange.
Since 2007, all the latest generation of Rolex Milgauss imitation watches have been equipped with the in-house self-winding caliber 3131. Protected by an antimagnetic cover, it drives the hours, minutes and seconds, and a stop-seconds mechanism ensures precise time setting. It is also equipped with a paramagnetic blue Parachrom hairspring to provide more stable and accurate timekeeping. This automatic movement has a 48-hour power reserve.
Rolex has equipped the Milgauss with an Oyster bracelet. This iconic triple-link bracelet is made of oyster steel and features a folding oyster clasp with an Easylink 5 mm comfort extension link. In addition to being designed for specific events, the Milgauss can also be used as an everyday watch thanks to its compactness, versatility and reliability.

The next important reference is the Ref. 18238, which looks almost identical to its predecessor but runs the cal. 3155 movement with Double Quickset function. With this movement, the wearer can adjust the date and day display via the crown without affecting the chronograph hands. With a number of other upgrades to the movement, the Day-Date 18238 ushered in a new generation of highly accurate Rolex President replica watches. 
The ref. 118238 marked the introduction of a slightly redesigned case and bracelet at the time of its launch. The new case features slightly thicker lugs (now with a highly polished finish) and the bracelet includes more robust links and an improved clasp.
Overall, the 6-digit series offers more weight on the wrist than its predecessors and marks an important transition in the Rolex President line. Despite the cosmetic updates, this generation continues to use the 3155 caliber, which was the movement of choice for the Day-Date until the release of the current 3255 caliber, which boasts a longer 70-hour power reserve and a more efficient Chronergy escapement.
The Day-Date 36 is currently produced under the number 128238 and features the latest movement. 128238 with the latest 3255 Perpetual movement. It also features all the traditional gold Day-Date design features, including the presidential strap, fluted bezel and double aperture on the dial. In addition to the movement, what makes the Day-Date in current production special is its carefully crafted proportions.
The final stop on our exploration of the famous Day-Date model is number 228238, which features a larger 40mm case. For decades, the Day-Date was produced in a 36 mm case. After briefly producing a 41 mm version of the watch with altered proportions, Rolex decided to produce the ref. 228238 in a 40 mm size, which restores the Day-Date’s classic proportions. Equally important, the traditional 36 mm version of the gold Day-Date is still in production today, adding further diversity to the Rolex President collection, along with its larger siblings.
Because Rolex gold copy watches require a serious investment, they are often the watches of choice for some of the world’s most successful and influential people. Want a watch that will make people exclaim “I’ve made it”? The gold Rolex President’s Watch is the watch to own. So many former U.S. presidents have worn the Day-Date, which is why the model is called “The President” in the first place. Rolex has even referred to the Day-Date as the “President’s Watch” in past advertisements.
The list of famous gold Day-Date watch wearers doesn’t stop there either. Everyone from golfer Jack Nicklaus to hip-hop mogul Jay-Z and even the Dalai Lama have been spotted wearing the coveted gold Rolex on their wrists. Women are also fond of presidential watches.

The Rolex Oyster Perpetual is an iconic timepiece that has been beloved by watch enthusiasts for over a century. First introduced in 1926, the Oyster Perpetual was the world’s first waterproof wristwatch, and it has since become a symbol of elegance, style, and precision. 
One of the most popular versions of the Oyster Perpetual is the entry-level model, which is an excellent choice for those looking for a high-quality watch that is both affordable and reliable.
The watch’s stainless steel case is durable and highly resistant to wear and corrosion, making it a reliable investment for many years. The smooth bezel and clear dial, available in various colours, add to the watch’s timeless design.
The replica Rolex Calibre 2231 movement inside the watch is highly accurate and reliable, ensuring that the watch keeps accurate time for an extended period. The watch’s power reserve of approximately 48 hours is more than enough for most wearers’ needs.
The entry-level Oyster Perpetual imitation comes in various sizes, ranging from 28mm to 41mm. The case is made of 904L stainless steel, highly resistant to corrosion and wear. The bezel is smooth and simple, with no additional markings or embellishments, giving the watch a classic and understated look.
Delving into its long history, you will find several precious metal versions in 9K, 14K and 18K gold – both yellow and pink. It was also one of the first copy Rolex watches released in Rolesor, the brand’s term for the two-tone fusion of stainless steel and yellow gold on a single watch. Today, all Rolex Oyster Perpetual watches are forged entirely from stainless steel, underscoring the brand’s longstanding status as an entry-level model.

Clean seems more reliable than other watchmakers like GM factory and BT factory in providing super clone Rolex watches like Submariner, Ditoner and Datejust, the quality of Clean Rolex is recognized by the customers. It won’t take too long to order from Clean, except for ordering the grey Ditoner from them; it seems like the grey Ditoner released by Clean factory a few weeks ago is still There is no stock, someone at the factory said a few parts are missing, so there is still a wait. Today, I will introduce the two new watches just released by Clean factory: the yellow gold Daytona and the Datejust.
This new yellow gold Daytona is different from the one previously released by Clean factory in that this new watch has a black dial. I find it odd that these two yellow gold Daytona were available immediately after the Clean factory release, but the grey Daytona released earlier is still unavailable; why? As far as I can tell, there is a lot of demand for the grey Daytona, more so than the two yellow-gold replica Rolex Daytonas. Many readers here asked me about the Clean grey Daytona after I posted the watch news. Still, each time I told them they had to wait after ordering this watch from Clean, I don’t know how long they had to wait, so I think many people switched to buying the grey Daytona from the BT factory.
The second new watch is the Rolex Datejust II from Clean, which has a new fresh, mint green face that is radially machined. This replica watch has a fluted bezel and a Jubilee bracelet made of solid 904L stainless steel. The middle 3 links of the bracelet are shiny and highly polished, contrasting with the brushed links on either side. The finish of the bracelet is the best in our market; it is made by the same factory that used to make bracelets for AR factory, the edges and corners of the bracelet are polished smooth with no sharp right angles, so the whole bracelet feels very comfortable to wear.

While neither Patek Philippe nor Rolex publicly released sales or production figures, industry statistics estimate that in 2017, Patek Philippe produced about 58,000 replica watches per year, while Rolex produced about 1 million watches. It puts the two brands in entirely different markets – Patek Philippe’s market runs on extreme exclusivity, while Rolex’s is driven by mass demand. However, we should point out that specific models and reference numbers of Rolex are produced in smaller and more exclusive quantities than others and that despite Rolex’s high production volume, demand still greatly exceeds supply. 
Rolex, on the other hand, is better known for its highly functional and iconic designs of sports and tool watches – think Daytona, Submariner, and Explorer. of course, Rolex also produces formal watches, and its sports watch collections often feature gold and two-tone designs that offer additional stylistic versatility without sacrificing any functionality. However, some of Rolex’s most popular models are the stainless steel sports fake watches, popular for pairing luxurious finishes with durable, accurate, and proven components that will last for years.
We could also point out that Patek Philippe has its own sports watches, such as the ultra-exclusive and fan-favorite Nautilus. But at the end of the day, Patek Philippe is more focused on luxury, complicated dress watches, while Rolex has a much sharper eye for luxury sports watches. The two brands have entirely different specialties (and price points), so it’s hard to say that one is “better” than the other.
Obviously, Patek Philippe is more expensive, but that doesn’t necessarily make them “better” overall.” Patek Philippe has been making watches for 180 years, while Rolex has only been around for 110 years,” notes Paul Altieri, founder of Bob’s Watches and a noted Rolex collector.
“But in that time, they have surpassed any other luxury watchmaker. Patek Philippe may still be at the top in terms of sheer prestige, but Rolex is more iconic and much cooler. Picasso wore a Patek, but everyone from Sir Edmund Hillary to James Bond and Steve McQueen wore Rolexes – they were action figures with effortless style and deadly charisma. There’s a rugged masculinity to these watches, and they’re very capable tools, too. There’s really no other watch like it”.
As Patek Philippe President Thierry Stern made clear in our recent article, Patek Philippe firmly defends its reputation for not pandering to the whims of the market. Schnipper notes that Patek Philippe takes excellent care of its customers and backs up its work with archival excerpts and other materials.” It’s something that other brands have a hard time doing,” Schnipper told the newspaper.” If you’re going to spend a lot of money, there’s this level of comfort. You have a lot more information about the piece. It’s hard to have a fake Patek Philippe, a no-frills fake.”
While counterfeit Rolexes are relatively common, there are still plenty of ways to fight back. Bain adds that Patek Philippe is “much more invested in the brand.” Rolex has it, with advertising, and so does Patek Philippe, but I think Patek Philippe is more invested in the heritage of its brand than Rolex is.”
When the Times posed this question, there was an interesting response: “Suppose someone had $10,000 to invest in a vintage watch. What would you suggest they buy?” Without hesitation, all three auction house bigwigs answered Patek Philippe. But Bain disagreed.” I think a replica Rolex sports watch would be a great investment. For example, if you buy a basic Rolex GMT or Submariner for $10,000 from a trusted source”-like Bob’s Watches-“a good condition example, it will double in value in the next five to seven years. Here’s my point. You can get a 1975 Submariner 5513 in good condition for $10,000.”
As for the future of vintage replica watches, Ms. Omura of Antiquorum fully supports Rolex’s view.” She says, “In the next six months to a year, for any of us here, it’s a Rolex Sport – there’s no question about it.” People speculate. They’re looking at a lot of things as investments. They’re buying something because they think it’s going to double in value.” For example, the Rolex Daytona Vintage is a pretty sure thing.

Rolex may have originally built its legendary reputation by making tough and reliable sports and tool watches, but the brand’s days as a maker of utilitarian timekeeping equipment are long gone. Today, fake Rolex is a full-fledged luxury brand, and it is arguably the single most famous luxury brand in the entire world. Considering the fact that countless people around the world cannot buy a Submariner, even though they are more than willing to pay full retail price, it almost becomes a travesty to think of a military branch supplying its troops with Rolex Submariner watches. In fact, the Rolex Submariner is in such high demand that most people are willing to pay well over the retail price of a brand new one just to skip the years of waiting lists and add it to their collection.
While Rolex is transitioning into a luxury manufacturer, it has never stopped producing reliable, well-made sports watches. However, the nature of its sports watches has certainly evolved into a more luxury-oriented approach, much like the brand’s positioning in the larger watch market. Rolex began producing sports watches back in the 1950s and 1960s, and while its products have always been considered fine timepieces, they have hardly considered luxury items, let alone status symbols.
Today, Rolex sports watches are some of the most iconic and popular luxury timepieces in existence, and wearing a Rolex sports watch has become a recognized symbol of success and personal achievement. Because of their implied connotations, modern Rolex replica watches need to do more than just be tough and reliable; they also need to offer something to shine and match the magnificent and unique image of Rolex itself.
The Yacht-Master 42 model 226659 is the wonderful poster child for the modern Rolex brand. Its monochromatic silhouette paired with a matte black ceramic bezel and black Oysterflex strap make this watch essentially casual and sporty, and at first glance, you’d be forgiven for thinking it’s a humble stainless steel model. However, Rolex is not a brand known for making exaggerated statement pieces. The white gold Yacht-Master 42 is the perfect statement piece for those who don’t want to make a statement, and that’s exactly why ref. 226659 is the perfect poster child for the modern Rolex brand.

The Rolex Cosmograph Daytona ref. 116500LN is one of the brand’s most coveted watches. Even though it was launched in 2016, it still takes a while to get a brand new piece from retailers. That’s why the pre-owned market for this watch is booming. Even so, pre-owned Rolex Daytona 116500LN watches are priced not too far from their original price, and sometimes even more expensive. A closer look at each of the watch’s parts will surely tell you why it is such a worthy piece to own. 
There is so much to love about both dials and, in all honestly, it is hard to choose between the two. They are both wonderful timepieces and it’s hard to pick just one if you have to pick one. The best way to know what is better for you is to see it in person and know which one appeals to you more.
With the change on the bezel, some people expected the layout to change as well. However, Rolex has retained the layout of the chronograph. The chronograph’s 30-minute sub-dial is located at 3 o’clock. In addition, the indicator for the running seconds is located at 6 o’clock. At the same time, you get a 12-hour counter at 9 o’clock.
Powering the replica Rolex Cosmonaut Daytona 116500LN is the Rolex Manufacture caliber 4130, the first in-house movement ever made by the brand. It is a self-winding mechanical chronograph movement that has been used in Rolex Daytona watches since 2000. The use of this movement marked the launch of the third generation of Daytona watches.
The great thing about the Rolex Calibre 4130 is that it is a monolithic workhorse. This means that it has fewer components and more reliable performance. The oscillator of this movement is equipped with the brand’s blue Parachrom hairspring. It is incredibly resistant to magnets. Therefore, it is a great choice when you are over a magnetic field. It is also resistant to any fluctuations in temperature, as well as shocks. Even if the temperature suddenly drops or rises, it remains very accurate. The accuracy of this movement is about +2/-2 seconds per day. This means that the movement is a certified chronometer.
With a power reserve of 72 hours, it is a very good watch to keep around. It remains faithful to its status as a timepiece made for racetracks and elsewhere.
