The Silent StopWatch is under warranty for one year from date of purchase for all defects. This warranty mirrors the original factory warranty, and will be invalidated due to signs of abuse or tampering, including signs of water infiltration. Under the terms of our warranty, the watch will be replaced or repaired at the discretion of SilentStopWatch.com, but the customer is responsible for shipping the watch for repair or replacement. If you are simply unhappy with the Silent StopWatch, please return it within 7 days of receipt. You pay return shipping costs, and a 20% restocking fee will be deducted from the amount returned to you.
