Decima Watch Co. offers a limited warranty on defects in materials, movement and workmanship for a period of two (2) years after you have taken physical possession of the watch from decima.store or an authorized Decima Watch Co. dealer. We also want to make sure we get your watch fixed if you encounter any problems with it, so we guarantee that we will keep sufficient spare parts to repair or replace it for two (2) years. This means that if the materials in your watch aren't right or if the watch isn't put together correctly, we'll repair or replace it, at our discretion. But, this doesn't mean you can abuse your watch and expect us to fix it for free. We don't cover normal wear and tear of the watch case, crystal, band or bracelets, battery replacements, loss or theft. You will void your warranty if you open your caseback, push the buttons underwater, forget to screw down or push in the crown. Proof of purchase is required for all warranty claims and service requests, so hold onto your receipt/warranty card. Decima Watch Co. will not accept a warranty claim or repair request if a watch has evidence of excessive wear or misuse.
