This watch has not lost a second in over a month! I orignally ordered a Wenger 62910-16908 and it didn't work when I received it. The Wenger 72900 is listed as 38mm crown, but it is the same watch as the 62910-16908 which is listed as a 41mm. Thusly, the 72900 is a large watch! I would much prefer a 38mm, but considering the quality of the watch, very nice leather band and and the excellent time keeping, I'll give this 4 stars.
