Flat sapphire crystal 1.4 mm

This 1.4 mm item targets a precise range: diameters from 26.0 mm to 33.5 mm, in 64 sizes. A slightly greater thickness than a thin crystal, without reaching that of the most solid crystals in the range.

Which watches is it for?

This combination is often found on men's wristwatches of classic size, notably sports or dress models whose bezel is designed for a slightly thicker crystal. It generally suits cases where the old crystal measures around 1.4 mm and 1.0 mm would be too thin to hold properly in the seat.

Sapphire in practice

What you gain

With a hardness of 9 on the Mohs scale, sapphire is highly scratch resistant: the surface stays clean even after years of wear. The 1.4 mm also gives it a little more material than a thin crystal.

What you have to accept

• more brittle behaviour than mineral crystal under a violent impact;
• a higher price, from €64.90 to €70.90 for this thickness;
• generally press fitted, with a suitable gasket.

Measuring, step by step

• Remove the old crystal or, if it is broken, clean the seat.
• Measure the diameter with a calliper across at least two axes.
• Measure the thickness at the edge.
