Owned this watch for a couple of months now.  Really simple elegant design that wears well, but with the black band has a little more sport to it. This Hamilton has a 38mm case diameter which is at the smallest end of the Khaki's (40 and 42mm) cases for men, but works well for people with smaller wrist or who simply don't like big cases. The case back is screw down and has an observation window to show off the 25 jewels Swiss movement (ETA2824) and the rotor.  My only complaint is that the highly polished ring around the dial tends to scratch pretty easily. Nothing you can't buff out with a cape cod cloth but kind of annoying for some. Other than that it is solid watch that it truly a classic.
