A 1970s Roamer Stingray Chrono Diver, equipped with a high powered column-wheel Valjoux 23 movement which was only used in the first year of production. This Roamer Stingray Chrono Diver has a unique fully stainless steel case that measures about 42mm in diameter, a signed crown, an inner minutes bezel which brings an amazing amount of depth, the “candy cane striped” minutes register hand, the Roamer trademark red slash at 20 minutes on the sub register, and the sharp centrally mounted chronograph seconds hand, all contrasted against a matte black dial and white font and hands fitted with the original signed crystal.
