Water Resistance:

       The highest quality of Japanese replica watches are water-resistant to 30 feet. This is both the usual resistance for average people, and how deep underwater the watch can get without cracks or leaks happening. However, purchasers also want to be able to wear their watch for everyday activities like taking a shower and getting caught in the rain. It would be a shame if you kept your watch on in the bathtub and it never worked again. To avoid this, be sure to read the retailer's information on how water-resistant their watches are. The honest ones will warn you not to get their watches wet-but they're also not selling high-quality replicas. The latter have seals around the crown and the lugs-this is important to ask about if you don't see it stated anywhere. Three Rolex models (Daytona, Sea Dweller, and Submariner) have a triple-lock crown which has an additional gasket in the crown tube threads. You can see in the photo below the basic screw threads (without the extra seal) that many replicas have.
