Simply put, until the bracelet and back case cover are removed, there is nearly no way to know for sure that the watch is authentic. It is only when you open a Rolex watch to reveal its movement and hidden parts, that you can see the characteristics that help to identify a genuine watch. A skilled examiner with experience will know immediately whether a Rolex is genuine by looking at the movement, which is manufactured in-house and is impossible to fake.

What exactly do our experts at Worthy look for inside a Rolex to check its authenticity?

Reference number versus the dial. A watch with a Rolex GMT reference number 1675 and a submariner dial looks suspicious. We will make sure the reference is correct to a specific watch model.

Genuine Rolex reference numbers

Serial watch number. The serial numbers, located between the lugs, should match the Rolex system and if paperwork is available, should match them as well. Furthermore, the engraving between the lugs of a genuine Rolex feature very fine lines. Some counterfeits will feature an etched appearance (sandy). In addition, the spacing on these numbers is often too close together and not even as on a genuine Rolex. Everything that applies to the serial number also applies to the reference number (model number).

Movement model versus watch model. On a genuine Rolex movement we will see a movement number. This is the movement model and it should correspond with a specific watch model.

Movement serial number. Every real Rolex have a clear stamped serial number on its movement. We will examine the quality of the stamping and the correct numbering.

Case back (inner) fonts and markings. A real Rolex watch carries the markings that correspond correctly to the brand.

The color of the wheels. In general, close examination of the inside movement will tell you a great deal about the authenticity and also the real condition of the watch.

The structure of the movement. There are hundreds of parts which compose this mechanical watch movement. An experienced watchmaker will be able to know if the overall movement is correct, if parts are not correct it will bring questions about authentications. There are many cases in which a fake movement was inserted into a genuine Rolex case making a frankenwatch.

Water pressure threshold. Comparing water pressure threshold to a specific watch rating (after checking the seals of course) is an indication that can easily be checked in an expensive Rolex. A fake Rolex won’t have that “diving” rating.

While we do not advise that you carry out these inspections on your own, it is good to know what your watch expert will be looking for when trying to spot a fake Rolex. Even more, the level of detail and work that goes into properly authenticating a watch. You can rest-assured after all of these tests that you are wearing a genuine Rolex, through and through. When you sell a watch at Worthy, all of these tests are conducted for you followed by an HD photoshoot and online auction to qualified watch buyers.
