In appearance a great clock. I have now worn for 3 years every day. The automatic lighting system is just great during night shifts. Unfortunately, the display has a loss now. The numbers are not displayed completely. Too bad ... The clock had to join a lot, a lot of punches and scratches has gotten and held still standing. If the indicator does not croaked I would wear them for years. Now I'll move to the variant GW-7900B-1ER. Let's see if they armed themselves in the service on the road longer ....
