This is a Hamilton wristwatch. I wore it on special occasions like weddings, so I didn't use it very often. It works without any problems. The leather strap was originally stiff, and as you can see in photos 3 and 4, it doesn't form a perfectly round shape that fits snugly around the wrist. This didn't cause any particular problems when I used it. It was like this from the time of purchase. Please note that there is no box or instruction manual, only the watch itself.
