I received this watch about a week ago and it stopped running that day. I reset the time and the next morning, it was 2 hours slow. I promptly sent it back to Amazon via UPS (no charge). I received full credit for the watch. I am very pleased with Amazon's return policy and prompt credit. As far as this watch goes, it is very sharp though larger than I thought it would be. I wish there was a quality check on the watch before it was shipped, probably had a bad battery.
