I sent one piece back to Trusty, which was received is horrible condition. You need to be very careful, follow the TD's instructions to the letter and have some valium on hand for keeping you patient throughout the process. 1. Be sure to request that the TD send you an address label in CHINESE, which you will add to the side of the box. 2. From the USA, I used USPS Priority Express, which cost me ~$40. It showed delivered in 7 days. 3. Even when it showed delivered, the TD did not acknowledge receiving it for several more days. 4. The repairs took several more WEEKS. 5. Then the typical wait for the shipping back to me. My return shipment originated in Hong Kong, so I'm guessing that's where Andrew has his repair shop. All in all, it took about 10 weeks for the round trip. All the issues were addressed and the watch has worked fine since. That being said, I would probably not do it again. Take the time to find someone to service it in North America, or take SSTEEL up on his offer. It'll be a lot less stressful, but you'll pay a few more $$$$$
