Sapphire Bezel Insert description:
Sapphire Crystal is very popular among wristwatches, Because of its amazing features:
- Very wide optical transmission band from UV to near-infrared, (0.15–5.5 µm)
- Significantly stronger than other optical materials or standard glass windows
-
Thinner and Stronger than Standard Glass Windows
-
Most sapphire glass found in wristwatches is actually synthetic (man-made) sapphire, rather than the naturally occurring material you may be familiar with. As with acrylic, this isn’t technically ‘glass’, rather, transparent crystallised Aluminium Oxide; usually produced in a laboratory. You will struggle to scratch a sapphire crystal with anything other than a piece of diamond.
Synthetic Optical Sapphire has no colouration and with a selection of grades of Sapphire available, transmission ranges from 170nm to 6 microns.
