Zenith vintage diver automatic watch. Ultra Rare Model. The watch is in great condition, near mint. Works perfectly. I have never seen a Zenith diver model with the same rotating scale. I believe the band is not original. The watch measure is approximately 37mm without the crown. The band is small, I have a small wrist and it´s on the limit. The ref or serial number displayed on the movement is 5972988 and caliber 2532PC, Let me know if any doubt. Thanks.
