Domed mineral crystal 2.0 mm

Some cases need a crystal with substance. At 2.0 mm, this domed mineral crystal is the thickest in our domed series without base.

Use and suitable watches

This type of crystal is often found on men's watches with a deep case, sports-inspired models or watches whose bezel has a wide groove. It generally suits cases where the original crystal also measured about 2 mm at the edge: fitting a thinner crystal in this seat would leave play. The range includes 65 diameters, from 18.0 mm to 50.0 mm.

Advantages and constraints

The thickness makes the crystal more rigid and gives it a solid feel. Mineral crystal remains a good compromise between strength and price, with a standard hardness of about 5 to 6 on the Mohs scale. It does, however, scratch more than sapphire crystal, and the dome, which sits proud of the bezel, takes most of the rubbing.

Another point to bear in mind: a 2.0 mm crystal takes up more height. If your watch hands are close to the crystal, check that the dome does not touch them once fitted.

The right way to measure

Diameter

With a calliper, measure the diameter at the base of the crystal, that is, the part that fits into the bezel.

Thickness

Place the jaws on the edge of the crystal, not at the centre of the dome, otherwise the height of the curve will distort the reading.
