This is a 39mm compressor style diver with an OEM SKX173 dial and a lumed INTERNAL rotating timing bezel. It comes with 3 textured straps to complete the vintage look. One grey nato, one mustard nato, and one forest green quick release FKM rubber strap. The lume is very bright and long lasting which is to be expected from an OEM seiko dial. Dimensions: 39mm diameter, 12mm slim, 20mm lug width, 47mm lug to lug. It’s super light and thin so it wears amazingly. The bezel is free rotating so there are no clicks and it can rotate in both directions for maximum efficiency. The firmness on the bezel is perfect. Just firm enough so that it won’t move by itself, but also easy enough to rotate without much hassle. Pressure tested to 100 meters and passed. Price: Negotiable $350 shipped to CONUS. I will ship within 24 hours of receiving payment.
