Not necessarily. If you wish to send it in to us to have your battery changed, we do FREE battery changes and cleanings for every watch that is sent in to our facility. You can request a battery change on our Repair Support page by filling out the Repair form here.
However, you can take your watch in to a local repair shop if its more convenient for you. Bands and battery changes do not void your warranty. If you need to take your watch somewhere local, we recommend taking your watch to a watch repair store - NOT a jewelry store.
If you get a battery change by a local business and the watch is damaged, it is the user’s responsibility to cover repair costs. Your warranty will be voided at this point.
