Gaskets Age Too
Even sealed in a drawer, gasket rubber degrades. Here is the storage-time reality.
Gasket Aging Factors
| Factor | Acceleration Effect |
|---|---|
| Oxygen exposure | Oxidation hardens rubber gradually |
| Ozone | Electronics and motors generate it — attacks double bonds in rubber |
| Temperature swings | Cycle expansion/compression fatigues material |
| UV light | Degrades polymer chains if stored near windows |
Timeline Reality
- Sealed watch, stable climate: gaskets remain serviceable 5–8 years
- Hot/humid storage: halve those estimates
- Previously opened watch: compression already set — replace gaskets at next service regardless of appearance
Practical Protocol
- Note the date of every case opening on your build log
- If 2+ years have passed since last seal refresh, budget replacement before next water exposure
- Storage improvement: airtight container with desiccant slows aging significantly — see our storage guide

Frequently Asked Questions
Can I see gasket aging?
Sometimes: whitening, surface cracking or permanent flattening indicate replacement. But internal degradation isn't visible — age-based replacement beats visual inspection alone.
