For all vintage dive watch collectors out there, this 1970's Zodiac Sea Wolf 20atm with orange chapter ring will be a wonderful addition to your collection. The case measures 39mm without crown and is in amazing original condition with near perfect factory finish. The dial is beautiful and clear, and the crystal is very nice as well, freshly polished. The crown is a factory non-screw down. I believe the movement is the 722-906 movement, and is running strong. It comes with a new 19mm NATO strap. Asking $750 OBRO shipped in the CONUS. Please feel free to reach out with any questions or make offers. You can reach me via PM or text/call 202.531.4343.
