Here we have a 1935 Waltham Riverside. The gold filled case measures about 31mm in diameter, not including the crown. Lug width is 16mm. Bracelet is one of those gold filled stretchy bracelets, and age appropriate. Movement is a high grade 21 jewel Riverside, with hand engraving. It was recently serviced, and keeps great time. I'm asking $150, try finding such a nice example at the price. My email is lefank at Yahoo or PM me for details.
