Battery Replacement:
Please refrain from changing the battery in your 40Nine watch yourself.  You may either bring it to a local reputable jeweler who can properly seal the case back to its original position after the battery is changed.  You may also send the watch to us for battery replacement. There is no charge for the battery replacement, however we do charge $10 for return shipping.  Please include your contact information so we may call you for a credit card or include a check for $10 made out to UWC:

Please include a note describing the issue you are having with your watch and your return address, as well as your phone number in case we need to reach you.
