Gold Plated Gruen Day / Night Jump watch. These are extremely rare. Go ahead and search yourself. After searching I only found 6 of these retailing worldwide. They are retailing for 595 USD and 695 USD at a dealer in Dallas and 757 CAD in Toronto. Another going for $400 USD and yet another for $1000 USD. The watch is clean and works fine. Some minor scratches on the acrylic face. I have been using for a month after retrieving from storage. I am the 2nd owner (after my Grandpa) and have had in storage close to 30 years. It works fine. (Windup watch). If you want proof of value let me know I can provide. Its a rare $700 piece. Contact via email@example.com if no answer on phone.
