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?

No. Once removed it has lost its mechanical properties. Always replace it.
