This o-ring watch case back seal assortment is a gasket kit for watchmakers and others who work on watch case backs. These round gaskets are made of solid tube rubber to create an airtight seal that prevents water from entering the watch case. They are flexible enough to fit not only round watch case backs but, square, rectangle and other fancy shaped case backs. As this assortment includes gaskets of various sizes, you should definitely be able to find a correct match for the gasket you need to replace.
Please confirm your watch case size before ordering !
First, before you order your new replacement gasket, you must measure the inside diameter of the back to ensure the gasket will fit tightly. Take the watch case back and place it upside down on a flat surface.
Before measuring the gasket, you will need to remove the old gasket if it has not already broken and fallen off on its own. Remove the old gasket by pulling the gasket away from the back with your tweezers and sliding it off the back.
