All our watches come with a standard 3ATM/30M water resistance which is suitable for everyday use such as rain and splashes.

If you want to use your watch for swimming snorkeling or bathing in the sea or pool you can upgrade to 10ATM/100M water resistance which provides extra protection for water activities.

When you choose the 10ATM upgrade your watch undergoes professional treatment to ensure it can withstand water pressure up to 10ATM/100M including pressure testing with professional equipment to verify water resistance replacement of seals and proper casing sealing as well as quality assurance with a guarantee on the upgraded water resistance.

Please note that any symbols or text on the dial are decorative and do not necessarily reflect the actual water resistance. The warranty does not cover water or moisture damage at 3ATM but covers such damage with the 10ATM upgrade.
