The watch crystal gasket holds the crystal in the bezel and contributes to case water resistance. Made from Hytrel, this gasket combines elasticity with long-term compression resistance. Essential for every crystal replacement.
Features
- Material: Hytrel, the reference watchmaker polymer.
- Outer diameters: matched to the inner diameter of the bezel.
- Inner diameters: matched to the crystal to be fitted.
- Various thicknesses to suit the seat.
How to choose
- Measure the inner diameter of the bezel with a calliper.
- Measure the depth of the seat to set the gasket height.
- Check that the inner diameter of the gasket matches the chosen crystal.
- Round to the nearest tenth of a millimetre.

FAQ
Should the crystal gasket be lubricated?
No. Unlike case-back and crown gaskets, the crystal gasket is fitted dry.
Can I reuse the old gasket?
