Upgrade to 10 ATM

All our watches come with a standard 3 ATM/30M water resistance which is perfectly sufficient for everyday use like rain and splashes.

However, if you want to wear your watch while swimming, snorkeling, or bathing in the ocean or pool, you can purchase an upgrade to have your watch built with 10 ATM/100M water resistance adding extra protection for water activities.

When you choose to upgrade your watch’s water resistance, a professional treatment is carried out to ensure it can withstand water pressure up to 10 ATM/100M. This process involves pressure testing the watch using professional equipment to verify water tightness, replacing gaskets and sealing the case where necessary, and quality assurance of all procedures with a warranty on water resistance after the upgrade.
