The Hamilton Sea-Glo is a handwinder with Hamilton 671 movement and has a beautiful embossed sunburst white dial. On a 60's Kreisler stainless steel bracelet. Textured dials were quite popular in the 50's and 60's. This Sea-Glo is an example of how a more ordinary-looking watch could be made interesting and distinctive. It came with either a white or black embossed dial.  

The 'Sea' part of the name is obvious. This is, or once was, a waterproof watch. The 'Glo' is referring to the luminous material used in the hands and the dots at each hour marker. Why Hamilton chose to leave the W out, remains one of the mysteries.
