Rolex watches never have a clear back, while fake Rolex watches may have a clear back.    Authentic Rolex watches never have engraving on the case back as well.   New Rolex watches will have a  hologram sticker on the case back.   The Rolex crown will be on the hologram above the watch’s reference number.   Fake Rolex’s will have a in-correct design on the sticker (if present).

Fake Rolex will be 1.5 times magnification, while a real rolex will be2.5 times magnification on the crystal, above the date.

Engraved between the lugs on the watch case are the reference and serial numbers are engraved . A Fake Rolex has acid etched numbers.   You can view this by removing bracelet of  the case.   You may need a pro to do this.

At the 6 o’clock position an etched Rolex crown on the crystal can be seen with a Rolex. In 2002 etching a crown into the crystal below the “6.” on the Rolex.  All Rolex watches have the crown etching by the end of 2003 to 2004.  Fake Rolex’s etching will not have the same features as an authentic Rolex. See Resources for a picture of a replica and authentic etching.

Unscrew the crown by turning it counterclockwise. If you have a Submariner, Sea Dweller or a Daytona, you will have a Triplock crown, which is a rubber gasket at the base of the crown. When the crown has popped out and is in the “neutral” position, you can see a black rubber gasket between the crown and the watch. A Rolex replica will probably not have this Triplock feature.
