Case width 40mm (excluding crown & crown guard), belt width 20mm. This is a men's size, not a boy's size. There are fine scratches on the case, but both the front and back glass surfaces are clean, and the visibility of the dial and internal mechanics is good. There are no problems with the operation or functions, including the day display, but the belt loop is torn. The belt, buckle, etc. are all genuine Hamilton m(_ _)m
