Markus Ruby offers a limited warranty on defects in materials and workmanship for a period of three (3) years after you have taken physical possession of the watch from markus-ruby.com or an authorized Markus Ruby 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 three (3) 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. This warranty does not cover normal wear and tear, the battery, crystal, watch case, strap, bracelet, loss or theft. You will void your warranty if you open your caseback, push the buttons underwater, or forget to screw down or push in the crown and expose your watch to moisture. Proof of purchase is required for all warranty claims and service requests. Markus Ruby will not accept a warranty claim or repair request if a watch has evidence of excessive wear or misuse. We know how much you love your Markus Ruby and if you are having technical issues with it, we want to get it repaired ASAP. Please click here to start the repair process.
