Rolex Authentication Guide

Rolex is one of the world’s most recognized and prestigious luxury watch brands. Known for their precision, finishing, and timeless design, Rolex watches are a symbol of success and status. However, with the popularity of Rolex watches comes the unfortunate reality of counterfeit timepieces. To ensure the authenticity of a Rolex, it is important to know how to authenticate it.

Trust Your Seller

The easiest way to avoid buying a reproduction or fake wristwatch is to purchase from a reputable and trustworthy seller. There are many reputable dealers, but it never hurts to do your homework to make sure you are getting an authentic watch. Google does an excellent job of showing you the most established and reliable retailers to avoid non-authentic models entering the market.

Think that’s enough? Think again. Your due diligence should not stop there. Most of these trusted dealers, including TBC wholesale, offer an authenticity guarantee for every sale. Our in-house buyers meticulously inspect each watch in our inventory and, when necessary, timepieces are restored and serviced by our approved service providers who use only 100% authentic Rolex parts. In addition, it is strongly recommended to find a dealer specializing in Rolex watches.

Be Wary of Reproductions on eBay

Websites such as Ebay and Craigslist are well known, but they are only platforms that connect buyers and sellers and are therefore not responsible for what is sold. These sites are often infested with fraudulent goods and it is difficult to find honest and trustworthy Rolex sellers. It can be a dangerous place if you do not already know how to tell whether a Rolex is authentic. For this reason, we never recommend eBay or Craigslist.

Check the Quality

Rolex is one of the most coveted luxury brands on the planet, and is known for its quality, durability, style, and prestige. The company uses the finest steel in the world, called "Oystersteel" (904L stainless steel), which is more resistant to rust and corrosion. Rolex also creates its own precious-metal alloys to ensure the exact integrity of each watch. Everything is made to perfection, so take a closer look at the case, crown, hands, bezel, bracelet, and clasp. If any element seems inferior in quality, you can be sure it is not a genuine watch.

Serial and Model Number Engravings

One of the best ways to ensure a Rolex is authentic is to refer to the case serial and reference numbers. The serial and model numbers of a genuine Rolex are deeply and perfectly marked with solid, very fine lines that shine in the light at a diamond-like angle. By contrast, the numbers on many counterfeit or replica watches are generally made up of tiny, weak dots due to a lower-quality marking process. In other cases, these numbers on counterfeit watches have a sandy appearance due to "acid etching," as shown in the photo above on the left.

In addition, another point worth mentioning is that counterfeiters often use the same reference and serial numbers on many watches of different styles. All authentic Rolex watches must have reference numbers that match their specific models and configurations, and each one will have its own unique serial number.

Where can you find your Rolex serial number?

The location of the serial number has evolved over time:

• Before 2005: the serial number is engraved on the case, between the two lower lugs (6 o’clock side). Removing the bracelet is necessary to read it.

• Between 2005 and 2008: the serial number is still often found between the lugs, but it can also appear, engraved, on the rehaut (the small inner rim surrounding the dial, under the crystal).

• From 2008 onward: the serial number is engraved only on the rehaut, around the dial. The watch must then be tilted under suitable light (ideally with a small lamp) in order to read it properly.

How to date your Rolex using its serial number

Until 2010, Rolex serial numbers followed a sequence that, in the vast majority of cases, made it possible to determine the year the case was manufactured. Simply compare the number engraved on your watch with the correspondence chart below: look for the closest serial number, below that of the watch, in the relevant column.
Since 2010, Rolex has abandoned this chronological numbering in favor of numbers and letters arranged randomly (“random numbers”), making it impossible to date a watch by this method alone.

Markings

Replica watches exist in different qualities, and very low-quality fake watches do not even bother to print the Rolex name or the famous crown logo on the watch. This is, of course, an obvious sign that you are dealing with an inauthentic piece.

Movement

If you open a watch, the movement should raise a red flag. The movement that powers a Rolex is an exercise in watchmaking mastery. A replica watch cannot match the craftsmanship, dedication, precision, and knowledge of a genuine Rolex caliber. Every authentic movement will always bear the engraved mention "Rolex", and the different components will have impeccable finishing (as you would expect), which you can only see if you open the watch.

It is also worth bearing in mind that the majority of Rolex watches feature mechanical movements. If you have a quartz watch in front of you, this may be a warning sign because only a very limited number of quartz watches have been produced throughout the brand’s history.

In addition, thanks to the use of modern technologies such as optical scanning and 3D printing, counterfeiters are getting better and better at copying Rolex models, with some of the most convincing examples even going so far as to "clone" the movement of a genuine Rolex. These watches (often called "super fakes") feature a movement that imitates the design and appearance of an authentic Rolex movement. However, upon inspection and magnification, the cloned movement does not have the ultra-fine precision finishing of the authentic movement (as well as its reliability and accuracy).

Dial, Hands, and Finishing

You can tell the watch on the left is fake because of the difference in quality. When first made, the dial of an original is more or less perfect, so if you see irregular fonts, inconsistent spacing between letters, spots, and/or spelling mistakes on the watch, that is a major red flag, and certainly a sign that you should start looking further into its authenticity.

In addition, fake Rolexes have less refined details and features. From the dial printing to the finishing of the hands and markers, every detail of a fake Rolex is not executed as well as on a genuine watch. That is why it is important to carefully study the official photos of the exact watch model you intend to buy. On some watches, the hands, dials, and bracelet clasps are very different.

Cyclops

The cyclops on the left does not enlarge the date enough. A real Rolex would enlarge the date by 2.5 times. The cyclops, in Rolex terminology, is the magnifying lens (on the crystal) located above the date window on the dial of their watches. On an authentic watch, the cyclops is convex and enlarges the date 2.5 times for better readability. If, on the watch you are considering buying, the magnifying lens is flat and the date is not enlarged as such, it is probably a counterfeit. To spot counterfeit watches, you must pay close attention to every detail.

Water Resistance

Rolex wristwatches are built to be water-resistant, while forged versions will not withstand a proper water pressure test. However, we strongly advise against using a water-resistance test if you doubt the authenticity of the piece, as this could damage the watch and prevent you from returning it. In addition, if a watch is old and requires repairs or servicing, there is a strong chance it will fail the water pressure test, even if it is authentic, so it is best not to try to do it yourself. If you think you have an inauthentic watch, have it inspected by a reputable professional.

Weight

An authentic Rolex watch will have heft because it is made exclusively from the finest materials, with no compromises in the production process. A counterfeit watch will be lighter and more fragile due to cheaper construction and lower-quality materials. If your watch lacks heft, you are probably dealing with a counterfeit.

Transparent Caseback

With the exception of a few very rare vintage models produced in the 1930s, Rolex does not equip its watches with transparent casebacks. Many counterfeit Rolex watches often feature transparent casebacks that let you see inside the watch and the different parts that make it work. Therefore, be wary of replica watches that feature a transparent window allowing you to see the movement at the back of the watch case.

Caseback Engravings

A real Rolex will almost never have engravings on the caseback. Engravings on the back almost always mean the watch is counterfeit. With the exception of a few rare cases, such as Rolex Sea Dweller, Milgauss, COMEX, military watches, and certain older rare models, Rolex does not engrave the outside of its casebacks with words, logos, or images (most of the time). If the watch you are looking at has engravings on the caseback - and they are not personal engravings from the previous owner, there is a strong chance that you have a fake Rolex or a replica-style imitation watch.

It is worth noting that some authentic vintage Rolex Datejust ladies’ models, such as models 6917, 69173, and 69174, bear the mentions "Stainless Steel" and "Registered Design" on their caseback. However, in most cases, the casebacks of genuine Rolexes are always smooth and are never engraved or transparent.

Micro-Engraved Crystal

In 2002, Rolex began micro-engraving a tiny crown logo at the 6 o’clock position on the crystal that protects the dial. If you are considering buying a Rolex made from 2002 onward, look for this marking as proof of authenticity. Because it is so small, it is difficult to see with the naked eye without the help of a magnifying glass, and suitable lighting is sometimes needed to see it properly.

The precision of this detail makes it difficult for counterfeit watches to reproduce and it should always be looked for when buying a modern Rolex. Look for the crown logo, and if you do not see it, go to a certified Rolex dealer for their professional opinion.

The Reference Number: What Does It Correspond To?

Another element to check is the reference number, engraved between the upper lugs (12 o’clock side). Unlike the serial number, which is unique to each watch, the reference number identifies the model and its configuration (material, bezel type, etc.), and must therefore be identical on all watches of the same model and execution.

This number is deciphered according to a logic specific to Rolex. For example:

• Reference 16613 (1985 Rolex Submariner gold/steel, nicknamed the "Sultan"): 166 designates the Submariner family, the 1 indicates a rotating bezel, the 3 indicates a gold/steel execution — possibly followed by "LB" for blue bezel and dial, or "LN" for black bezel and dial.

• Reference 116500 (Rolex Daytona steel): 1165 designates the Daytona family, the first 0 indicates a fixed bezel, the second 0 indicates a steel execution.

Main reference families by model:

Bezel type (digit after the first 3 digits of the reference):

Material (last digit of the reference):

Authenticating a Rolex

In addition to advice on spotting a counterfeit, it is also important to keep certain elements in mind to make sure you are buying authentic Rolex watches. While this is never an issue when you buy from TBC Wholesale, it is always useful to arm yourself with a bit of knowledge. We have therefore compiled a quick recap of the anatomy of authentic Rolex watches with a few basic guidelines to keep in mind. Please note that these rules only apply to Rolex watches made after 2002.

THE METALS OF AUTHENTIC ROLEX WATCHES

As expected, Rolex uses only the finest materials for its watches. For example, Rolex watches use exclusively 904L stainless steel and 18k gold. In addition, Rolex also uses a patented rose-gold alloy mixed with platinum, which the brand calls Everose. For Rolex watches in platinum, only 950 platinum, made of 95% pure platinum, will do. The term Rolesor refers to the use of both gold and stainless steel on a particular model. By contrast, the term Rolesium refers to the use of both platinum and stainless steel on a specific watch.

• 904L stainless steel

• 18k gold

• Everose rose-gold alloy (18k)

• 950 platinum

• Rolesor: gold and stainless steel (available in all 3 gold colors)

• Rolesium: platinum and stainless steel

• Good to know: the fluted bezel is never made in solid gold only.

THE OYSTER CASES OF AUTHENTIC ROLEX WATCHES

Rolex Oyster Perpetual watches are, of course, famous for their water resistance. In fact, Rolex made history in 1926 by creating the first waterproof wristwatch. Today, Rolex Oyster Perpetual watches have a minimum water resistance of 100 meters (330 feet). However, Rolex diving watches have much greater water resistance. The Rolex Submariner is water-resistant to 300 meters (1,000 feet), while the Sea-Dweller is water-resistant to 1,220 meters (4,000 feet). Finally, the Rolex Sea-Dweller Deepsea is water-resistant to 12,800 feet (3,900 meters).

• Rolex Oyster Perpetual minimum water resistance: 330 feet

• Submariner water resistance: 1,000 feet

• Sea-Dweller water resistance: 4,000 feet

• Sea-Dweller Deepsea water resistance: 12,800 feet

To achieve this level of water resistance, the cases of authentic Rolex watches have certain characteristics. First, they feature a solid center case. Second, they have a screw-down fluted caseback. Finally, the cases are equipped with screw-down winding crowns to prevent water from entering. Depending on the model, there is either the Twinlock or Triplock screw-down winding crown, with two or three sealed zones respectively.

• Twinlock: Day-Date, Datejust, Oyster Perpetual, Sky-Dweller, Pearlmaster, Explorer II, Milgauss, Air-King, GMT-Master II (pre-2008)

• Triplock: Yacht-Master, Yacht-Master II, Submariner, Sea-Dweller, Daytona, GMT-Master II (post-2008)

THE SAPPHIRE CRYSTAL OF AUTHENTIC ROLEX WATCHES

Modern authentic Rolex watches are equipped with scratch-resistant sapphire crystal that protects the watch dial. In addition, on date Rolex watches, a magnifying lens is placed above the date window to enlarge the number for better readability. This lens, called the Cyclops, is also made of sapphire crystal and magnifies the date 2.5 times. Until very recently, the only Rolex date models that did not have a Cyclops lens were the Sea-Dweller and Deepsea. But that changed at Baselworld 2017 when Rolex introduced the new Sea-Dweller with a Cyclops lens. Now, the only Rolex date watch without Cyclops crystal is the Sea-Dweller Deepsea.

Starting in 2002, Rolex began including a tiny micro-engraved Rolex crown, also known as the "coronet", on the crystal at the 6 o’clock position. Extremely difficult to see without a magnifying glass and almost impossible to reproduce correctly, this mini-marking is a hallmark of authentic Rolex watches. Another authenticity marking is found under the sapphire crystal on the rehaut, which is engraved all around with "ROLEX ROLEX ROLEX", as well as the serial number engraving at 6 o’clock.

THE BRACELETS OF AUTHENTIC ROLEX WATCHES

The bracelet of a Rolex watch is an integral part of its overall appearance. Today, there are many different bracelet types to choose from depending on the model. Here is a quick cheat sheet:

• Oyster bracelet: flat three-link construction. Available in steel, gold, platinum, or Rolesor.

• President: semi-circular three-link construction. Available in gold or platinum.

• Jubilee: curved five-link construction. Available in steel, gold, or Rolesor.

• Pearlmaster: rounded five-piece links (exclusive to Pearlmaster watches).

• Leather: alligator leather. Available with gold folding clasps.

• Oysterflex: nickel and titanium metal blade covered with black elastomer. Available with gold folding clasps.

• The newest Rolex bracelet option is Oysterflex. It debuted in 2015 on the Everose Yacht-Master and later became available on gold Daytona models. We hope that this quick guide to the anatomy of authentic Rolex watches will be useful to you. However, when looking for authentic Rolex watches, nothing beats buying from a trustworthy source, since all the homework has been done on your behalf.

Six red flags to look for on fake Rolex watches

Before starting the authentication process for a watch, it is worth keeping in mind a few essential tips and tricks that will help you spot obvious counterfeits right away:

1. Weight: genuine Rolex watches generally weigh more than most fakes.

2. The sweeping motion of the seconds hand: there should be no jerky movement (with the exception of Oysterquartz watches).

3. The cyclops lens on the crystal: the date on authentic Rolex watches is enlarged within the cyclops lens on the crystal and should almost completely fill the bubble.

4. The crown on the crystal: on newer Rolex watches, a small crown is laser-etched on the crystal at 6 o’clock.

5. The model and serial number: on all Rolex watches, you will find the model number (at the 12 o’clock side, where the bracelet meets the lug) and the serial number (at the 6 o’clock side, where the bracelet meets the lug, or on the inner bezel of newer Rolex watches). You should also look for the "Original Rolex Design" engraving above the model number. To learn how to remove the bracelet from your Rolex watch and find the serial and model numbers, see our video "How to Find the Serial Number and Model Number of a Rolex".

6. The details: everything about Rolex watches, whether new or pre-owned, is perfect (that is how Rolex does things). Make sure the lettering and details are immaculate in every aspect of the watch.

Real or Fake Rolex Watches

Strong demand also attracts a booming counterfeit market and, unfortunately, buyers can be caught out and hand over their money for a fake Rolex while believing it is real. So, if you have decided to invest in a Rolex, it is important to take the time to understand what you are buying. Consult the information below provided by our Rolex expert, who has more than 30 years of experience. All watches presented on our site come with a certified authenticity report upon request.

Rolex watches are one of the most coveted luxury items in the world. As a result, there is a huge market for replica (fake) watches. Most of these fraudulent watches are manufactured in China, but research shows that production is spreading throughout Asia and other regions as well. These fake timepieces usually sell for between $25 and $200, and their quality has improved in recent years. The modern Rolex Datejust collection and the Rolex Submariner are prime targets for these replicas.

Even experienced dealers can be fooled by fake watches. Some counterfeits are easy to spot right away, while others, more sophisticated ones, can be much harder to identify. That said, it can be difficult for a novice to tell whether a Rolex is fake. To help protect you from dishonest sellers and imitation products, we have put together a list of the distinctive signs of an authentic watch. Read this list carefully to make sure you are not being deceived by counterfeit watches.

Eliminating Risk When Buying Authentic Rolex Watches
