It features a sun-brushed, lacquered blue Vertical Teak dial with a date window at 3 o’clock, protected by a scratch-resistant sapphire crystal. The 38.5mm stainless steel case pairs with a stainless steel brushed bracelet. Powered by the Master Co-Axial calibre 8500, it's resistant to magnetic fields over 15,000 gauss, visible through the transparent caseback. This Ref. 231.13.39.21.03.001 is in excellent pre-owned condition, showing very minimal signs of wear. Perhaps some light scratches on the caseback and bracelet. It comes with its original undated papers. While service history is unknown, it is running excellent at +4 seconds/day with 305 amplitude. The watch includes an original Omega OEM deployant clasp.
