Hi Armida, Batteries are typically between $10-$15 and all come with a one year warranty. Higher grade watches ex. Movados, tags, and Cartier will run more and depend on the level of labor needed to change the battery. As Ron mentioned there is no guarantee on the water resistance but we do check the gaskets and apply silicone to them to try and guard against leaks. No establishment that changes batteries guarantees water resistance unless the watch can be pressured sealed, which we offer, at an additional charge. Not all watches can be pressured sealed.
$10.00. Be warned, they don't offer any guarantee of water resistance after battery replacement.
