An assorted mix of round O-ring sizes between 10mm and 30mm, so there's a strong chance of finding a match for most watch case backs, crowns or pushers needing a round rubber seal. A dab of silicone grease on the gasket before fitting helps it seat properly and extends its working life.
⚠️ Please check the diameter and thickness of your old gasket against the size you need before fitting, as this pack is a mixed assortment rather than a single fixed size — if you need flat-type gaskets instead of round, these are a separate product.
