Just the Gasket
Full crown replacement needs stem work; a gasket-only refresh doesn't. Here is the targeted maintenance.
When Gasket-Only Makes Sense
- Crown screws down fine but water testing fails
- Gasket visibly flattened, cracked or chalky
- Annual preventive maintenance on dive-worn watches
The Process
- Unscrew/pull the old gasket from the crown's groove — dental picks or fine needles work
- Clean the groove: old lubricant and debris prevent new gasket seating
- Match dimensions: inner diameter, cross-section thickness — see our gasket guide
- Lubricate thinly with silicone grease before fitting — see our grease guide
- Roll it into the groove without stretching excessively
When Full Replacement Is Smarter
- Crown threads worn or damaged
- Stem issues present — bundle both jobs
- Crown tube itself corroded
