A universal rubber O-ring seal for watches needing a larger-diameter gasket — commonly used on case backs, crowns or battery compartments. Gasket sizes are given as inside x outside diameter in millimetres, so measure your existing seal and compare before ordering to make sure the large size here is right for your watch. For an even better seal, these can be paired with a silicone watch grease (sold separately).
⚠️ Please check the exact inside and outside diameter of your original gasket in millimetres before buying, as this listing covers the large size only and case, crown and battery gaskets vary widely between watches.
