These gaskets sit between the case back and the watch case to renew a worn or perished seal, helping restore water resistance. The box offers a wide spread of diameters from 16.8mm up to 40.8mm, so most standard case-back sizes within that range are covered.

• Set 1: 0.6mm thick, 0.35mm width
• Set 2: 0.8mm thick, 0.35mm width
• Set 3: 1.25mm thick, 0.4mm width

Silicone grease (sold separately) can be used with these gaskets to help seal and extend gasket life.

⚠️ Please check the exact diameter, thickness and width of your old gasket before fitting, and select the matching thickness/width set at purchase, as the three variants are not interchangeable.
