Our warranty is simple and straight forward: If anything goes wrong with your REACTOR watch in the first two years of ownership, we will either repair it or replace it at our expense.

Here’s the “not so small print”: broken crystals, dead batteries, abuse and normal wear and tear are not considered manufacturing defects and are not covered by our warranty.

If your watch needs service, return it along with a copy of the REACTOR Service Return Form to:

5312 Derry Ave.
Suite B
Agoura Hills, CA 91301

If you have questions about service or if your repair is covered under warranty, please call us at 800-291-6600. When returning your watch, make sure it is packed securely in a padded envelope or box and insured for the full purchase price. Our service center is committed to returning your watch within 7 days of receiving it.

All REACTOR watches using a quartz movement do require a battery to operate. If your watch does need a new battery, we suggest you return the watch to us or have a qualified jeweler replace the battery for you. Because all REACTOR watches are water resistant to at least 100M, it is very important the seals inside the case are put back properly after the battery is replaced.

Our service center offers battery replacement and a thorough check-up of your REACTOR watch for $20; this charge includes battery replacement, inspection of case seals, crown and movement, cleaning and the cost of returning the watch to you by US Priority Mail. Please use the REACTOR Service Return Form when requesting this service.
