There are more and more replica watches in the market these years, but how to tell them apart? Here are some useful ways for your reference:
1. Movement 
The movement that powers a Rolex is an exercise in master watch-making skill. A fake watch cannot match the craftsmanship, dedication, precision, and knowledge invested into each genuine caliber bona fide movement will always have “Rolex” engraved on it, which you can only see if you open up the watch.
2. Serial & Model Number Stamping
The serial and model numbers on a genuine Rolex are deep and perfectly marked in solid, very fine lines that will actually glow in the light at an angle like a: diamond cut edge. On the contrary, the numbers on a fake, or replica, are typically made up of faint tiny dots because of a lower quality marking process. In other cases, these numbers on counterfeit watches will have a sandy-like appearance from being “acid etched” as shown in the photo above on the left.
Other factors should be considered is that a large number of the brands watches have mechanical movements, so if you’re looking at a quartz, that could be a red flag since only a very limited quantity of quartz watches throughout their history have been manufactured.
3. Dial
The dial of an original is clear, so if you see any uneven fonts, inconsistent spaces between the lettering, smudges, and/or misspellings on the watch then it is completely a fake rolex.
4. Weight
A genuine Rolex will have some weight to it because they are exclusively manufactured from the finest materials. A cheap replica watch will feel lighter and flimsy due to cheaper construction materials. If your watch doesn’t have any heft to it you are likely dealing with a replica model.
5. Cyclops
The Cyclops, in Rolex parlance, is the magnifying lens above the date window on the face of their watches. On a genuine timepiece, the Cyclops is convex and magnifies the date 2.5 times for ease of readability. If the magnification lens is flat on the watch you’re considering, and the date isn’t magnified as such, then you are dealing with a forgery. To spot counterfeit watches you need to pay close attention to every detail.
6. Waterproof
Rolex wristwatches are built to be waterproof, while forged versions will not withstand a proper water test. However, we strongly discourage using a water test if you doubt that the piece is real since it will likely ruin the watch, preventing you from being able to return it. If you believe you have a non real timepiece have it tested by a noticeable professional.
