There is no doubt this is a "rare" watch but valuable? I'm not so sure. They started asking multiple thousands and my curiosity got the better of me when the price hit $900US.
First, clearly not a compressor case. It has multiple o-rings so it was "waterproof" to a certain extent but not a full dive watch to my mind. Some signs of water incursion (no serious corrosion, thankfully) so it clearly saw at least some water time. I'll get it serviced. It's interesting enough to add to the collection. Am I going to search the earth looking for a mint version? Nope!
