A Touch of Grease
Gasket lubrication is the difference between smooth caseback threads and gritty ones — and between reliable and unreliable water sealing.
Where Grease Goes
| Location | Purpose |
|---|---|
| Caseback gasket | Smooth screwing; even compression |
| Crown gasket/tube | Seal integrity; easy screw-down |
| Bezel underside track | Smooth rotation feel |
What NOT to Grease
- Crystal seat: dry press fits better; lubricant invites slippage
- Movement itself: watchmaker's domain — different oils for different jewels
- Spring bar tips: attracts dust into lug holes
Product Types
- Silicone grease: the standard for gaskets — neutral, non-migrating
- Watch-specific brands: consistent quality worth the small premium
- Avoid petroleum products: they degrade rubber over time
Application is minimal: a thin film wiped around the gasket, not a coating. Excess collects debris. Gasket fundamentals in our gasket guide; crown specifics in the crown guide.
Frequently Asked Questions
How often to re-grease?
Every time the case opens — fresh gasket gets fresh grease as a package.
Too much grease symptoms?
Gritty rotation from debris attraction, or gasket slippage out of its channel.
