Domed mineral crystal with base 2.0 mm

For watches with a thick, curved crystal

The 2.0 mm domed crystal with base generally suits watches whose original crystal is both thick and topped with a dome. It is often found on sturdy men's watches and sports models, in diameters from 20.0 mm to 50.0 mm (61 sizes in the catalogue).

Strengths and weaknesses

The design is based on a flat base seated in the bezel, from which a domed section rises. At 2.0 mm, the edge is well defined and the crystal is more rigid than the thinner versions in the same family.

The material is mineral crystal with a standard hardness of about 5 to 6 on the Mohs scale. It offers a good balance between strength and price. It does, however, scratch more than sapphire, and the dome, which sits proud of the bezel, is exposed first.

Please note: the crystal alone does not make a watch water resistant. Water resistance also depends on the gasket and the fitting.

Taking the right measurements

Take a calliper and proceed as follows:

1. Measure the diameter of the old crystal at its base, edge to edge across the flat base.
2. Measure the thickness on the flat edge.
3. Compare the profile: a visible base confirms this shape is the right choice.

If in doubt about the shape or material, the page on crystal types will help you decide, and the measuring guide explains how to measure.
