Gasket Sealing Protocol
Installing a gasket correctly is the difference between reliable sealing and a leak disguised for months. Here is the protocol.
For Caseback Gaskets
- Clean the channel: remove old grease and debris from the caseback groove — residue prevents even compression
- Lightly lubricate: silicone grease on the gasket surface only — see our grease guide
- Seated evenly: gasket must sit in the groove without twisting or overlapping
- Tighten gradually: thread engagement first, then firm pressure — never gorilla-force
For Crystal Gaskets
| Crystal Type | Sealing Method |
|---|---|
| Press-fit crystal | Gasket compressed between crystal and case seat by press |
| Screw-down crystal | Crystal threads compress gasket directly |
| Tension-ring crystal | Spring ring holds crystal against gasket — older technology |
The Visual Test
After installation, check for:
- Even gasket visibility — no bunching or twisting visible
- Crystal sits flush — no gaps at any point around the edge
- Caseback threads engage smoothly — grittiness means gasket interference

Frequently Asked Questions
Can over-greasing cause leaks?
Excessive grease attracts dust which compromises the seal — thin film only, wipe excess.
