Found my first Zodiac the other day in a bag of watches for $15. Runs nicely, quite dirty but looks like it will clean up amazingly. It's really just the crystal thats banged up. The case still has the factory finish on the bezel and has never been polished, dial is original, as is the crown. Overall a great watch but I know nothing about it! I assume 1960s? Also, I tried for the life of me to get it open but it does not budge. My case knife is useless, there's notch on the case back to pop it off but as I said I can't get it and don't want to scratch anything up too badly. I found one other example online that sold on Ebay but it was a clear redial and they claimed it was a divers watch? But it's not is it? Anyone seen this Zodiac before? Finally it came on this gnarly strap, probably been on there for a longg time as the amount of verdigris was A LOT.
