Watch Crystals

Finding the right replacement crystal

This catalogue brings together 42 watch crystal products, available in 5246 diameters in total, from 9.6 to 50 mm. Prices range from €5.90 to €76.90 inc. VAT depending on material and size.

• Mineral crystals: flat, domed or domed with base, hardness of approximately 5 to 6 on the Mohs scale.
• Sapphire crystals: flat only, hardness of 9 on the Mohs scale.
• Acrylic crystals (hesalite): flat, extra-thin or domed, softer but can be polished.

The safest approach is to identify the material of the original crystal first, then its shape, and finally its thickness and diameter. Replacing a crystal with a different material is still possible, provided the shape and thickness remain compatible with the bezel and the gasket.

The diameter is taken with a calliper, to a tenth of a millimetre: see our guide to measuring a crystal. If you are unsure about the material of your current crystal, the guide to crystal types describes the clues that tell them apart.
