Guide by thickness

0.8 mm: from 13 to 41.5 mm.
0.9 mm: from 21.1 to 33.5 mm.
1.0 mm: from 13 to 45 mm, the widest range.
1.4 mm: from 26 to 33.5 mm.
1.5 mm: from 17 to 45 mm, plus an anti-reflective version in 23.5 mm.
2.0 mm and 2.4 mm: from 18 or 17 mm up to 45 mm.

Neighbouring thicknesses (0.8 / 0.9 / 1.0 mm or 1.4 / 1.5 mm) are not interchangeable without checking: a few tenths are enough to change the fit in the bezel. So measure the existing crystal accurately.

The guide to measuring a crystal describes taking dimensions with a calliper. To compare sapphire and mineral, read the page on crystal types.

Frequently asked questions

Can a 0.9 mm sapphire replace a 1.0 mm crystal?

Not without checking: a difference of a few tenths can change how it sits in the bezel. It is best to match the original thickness.

Is there an anti-reflective flat sapphire?

Yes, in 1.5 mm thickness and in a single diameter, 23.5 mm.

How do I measure the diameter of a sapphire crystal?

With a calliper, on the removed crystal or on the bezel opening, reading the value to a tenth of a millimetre.

Is sapphire scratchproof?

Its hardness of 9 on the Mohs scale makes it highly resistant to everyday scratches, without making it immune to impacts.

What is the price range for these crystals?

From €11.90 to €76.90 inc. VAT, depending on thickness and diameter.
