Mini O-Ring Watch Crown Gaskets Assorted Kit
These mini o-ring watch crown seal refills are made to be used with Japanese style crowns. Refills make it easier for the watchmaker to keep the most popular sizes on hand. These o-ring seals can save a watch when the genuine crown is no longer available, simply replace the gasket and make the crown water resistant again. These small round gaskets are made of solid tube rubber to create an airtight seal.
