Glues and greases

Gluing and lubricating in the right place

Fitting a crystal often involves two complementary products.

• Crystal glue fixes a date magnifier (cyclops lens) onto the crystal or holds a crystal or bezel in place. GS Hypo Cement, with its fine metal applicator, allows precise application and dries clear. Always use a minimal amount on clean, degreased surfaces.
• Gasket grease lubricates water-resistance gaskets each time the watch is opened. It makes refitting the gasket easier and helps keep the case water-resistant. Lubrijoint comes as foam impregnated with silicone grease and is easy to use.

A hardened, flattened or split gasket should be replaced rather than greased. For diving watches and watches exposed to high pressure, have the water resistance handled by a watchmaker.
