Product Description

These flat black rubber gaskets generally fit into a groove or recess in the back of the case and are most commonly used with a threaded case back. Simply measure the inside diameter and outside diameter of the groove that the gasket fits into on the case. Subtract the inside diameter from the outside diameter then divide in half to find the thickness of the gasket you need to fit your watch case. With 100 different diameters and multiple thicknesses in this kit, you should be able to find a gasket to fit your watch. 

Note: Diameter measured is the interior diameter of the gasket
