HAMILTON Hamilton Vintage Watch Small Second Manual Winding 10k Gold Length: 3.2cm, Width: 2.6cm The strap is an older, gold-plated, expandable strap from another company. However, I will also include another set of a current 17mm wide SEIKO lizard brown leather strap. I haven't used it much, but I have confirmed that it works. This is a vintage manual winding watch, so you may need to wind it two or three times a day. I do not guarantee completely accurate timekeeping. Overhaul history is unknown. It did not significantly lose or gain time during approximately half a day of use. There are some scratches, so please check the images.
