Overall, this is a handsome and solid quality watch. I believe the stats indicate it is 41mm but it looks a bit smaller, but not too small,  on the wrist. Not unusual with a watch that has a bezel for it to appear smaller since the bezel consumes part of the overall size.  One reviewer commented that the face was busy. I have not found that to be true. I bought the watch because of the automatic movement with full day and date. I think the watch has a classy look. Hamilton has an extensive offering of excellent watches at decent price points. This watch looks like it cost much more than it did. Also, I don't believe the specs mention that the watch has clear back case.  You can see the movement whirring away while you are not wearing the watch. It's a pretty cool feature.  I'm a desk diver so I can't speak to water resistance since its never been an issue for me with any watch. The description is a tad light, but rest assured, this is a full featured watch at a great price. You can't go wrong with a Hamilton.
