At the beginning of I was very happy. But my gladness has lasted no long. Already a first day I noticed that the watch has the time lag in 5-6 minutes per day, though I made all by instruction and used it no less than 8 hours in a day. After one week the watch quite stopped and no more to winded - inside something broke! I was not thought that it may happen with Japanese goods... As my purchase is not from Japan, the seller not provide any guarantee. Now only repair.
