Il nostro test di pressione:

Sapphire glass is a super dense, super scratch-proof type of glass: however it is important to check its water resistance.

We check against:
- for our Lady/Sapphire vintage watches: up to 3-5 ATM
- for our professional sportive watches: up to 10 ATM

Feel free to contact us for any specific question related to the subtest of a specific watch.
