Vintage Roamer Stingray Ref. 401637 automatic movement wristwatch with quick change day and date, roman numberals at 12, 6 and 9 o'clock. Sapphire crystal with dodecagonal bezel (signature of the current Stingray watches)  in stainless steel case with high grade dial (cross between sunburst and guilloche). ETA 2836-2 movement with Incabloc shock protection. Serviced about 6 years ago and worn infrequently (i.e. not on a winder) but still runs great (about 260 degrees amplitude). Smaller than the current version (I think it has gotton to Mark III) about 35mm diameter. Newblack croco pattern leather strap.
