Flat Mineral Crystals

Choosing a flat mineral crystal

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.
