I really like thiis watch. I'm sure the band will need to be replaced regularly but various NATO bands are available all over the net. The watch is very accurate, +/- 3 seconds/day but I'm sure individual results will vary. If it ever becomes less accurate getting it adjusted is easy and cheap and should be a part of the annual pro-service anyway. I had that read that this model would stay wound for 36-48 hours but mine has never lasted longer than 12 hours. Still a very nice timepiece for the money.
