Highlights
- Watch back O-ring and crown gasket
- Silicone grease lubricant
- Repair tool included per the title
- For case-back sealing and waterproofing
Best for
A watch hobbyist who changes batteries and wants to restore the case seal.
Things to consider
- The title does not list gasket sizes, and an O-ring of the wrong size will not seal, so measure your case back before ordering.
- Tip: a new gasket does not make a watch swim-ready by itself; real water resistance should be pressure tested, which this kit cannot do.
- Standard delivery from China to the US usually lands in roughly 1 to 3 weeks. You check out on AliExpress, so any refund claim runs through its Buyer Protection process. Low-value parcels are no longer duty-free in the US, so the final total can be higher than the listed price.
