Warranty periods range from 12 months to lifetime, depending on the brand. All of the brands we carry come with their international manufacturer warranty.* All warranty issues are to be handled directly with the watch manufacturer, so be sure to keep your electronic invoice for proof of purchase from Watches.com as we're an authorized retailer.
