The flat crystal is the most common shape on watches with a modern case. This category offers 12 products and 2255 diameters, from 10 to 50 mm, from €5.90 inc. VAT up to €13.90 inc. VAT for some large, thick diameters.

Thickness and finish

0.7 to 1.3 mm: for slim watches and small diameters.
1.5 to 2.5 mm: medium thicknesses, common on dress and sports watches.
3.0 to 4.0 mm: thick crystals, available from 17 or 25 mm depending on the product.
Chamfered 1.5 mm: bevelled edge, from 22 to 34 mm.
With rim 1.0 mm: from 21 to 34 mm.

Match the thickness of the removed crystal, measured on its edge. Look at the edge too: a visible bevel points to the chamfered product. The hardness of mineral, approximately 5 to 6 on the Mohs scale, is the same whatever the thickness.

The diameter is taken with a calliper; our guide explains how to go about measuring a crystal. Unsure about the material? See the page on crystal types.

Frequently asked questions

How do I measure the thickness of a flat crystal?

Place the edge of the removed crystal between the jaws of the calliper and read the value to a tenth of a millimetre.

What is a chamfered crystal for?

The chamfer is a bevel on the edge of the crystal. Choose it if the original crystal has this bevel, to keep the same look and fit.

Which thickness should I choose if I no longer have the original crystal?

Measure the depth available in the bezel and check the clearance above the hands. If in doubt, a watchmaker can confirm the dimension.

Should I change the gasket?

If the gasket is hard, split or deformed, it is best to replace it to ensure the new crystal is held securely.

Which diameters are covered?

The products cover diameters from 10 to 50 mm, with a specific range for each thickness.
