Battery Replacement

We recommend that you take it to a local jewelry store in order to insure it will maintain its water resistance. Improper battery replacement or service will void the warranty. If you feel comfortable replacing your own batteries, be careful to notice how the old battery comes out and the proper positioning of the hold-down contacts before removing it. Also, be careful to line up the O-ring gasket properly before replacing the battery door cover. To insure water resistance, it's a good idea to smear a small drop of silicone lubricant spray on the rubber O-ring.
