Bussora has a limited warranty that covers manufacturer's defects for two years after the original purchase date from an authorized dealer. Basically, if the watch parts or mechanics don't work properly, and it's our fault, we will repair or replace your product for free. However, this does not cover any abuse you might put your watch through on your own. The warranty does not cover water damage, normal wear and tear, batteries, accidental glass damage, scratches, strap damage, or theft. Proof of purchase is required for all warranty claims and service requests, so please keep your receipt. If you've purchased from our site or Amazon, the order number will suffice; otherwise if you purchased via another authorized seller or retail location, you will need to contact them directly as they handle their own warranty claims, returns and exchanges.
