Thanks much John and contrats on the new watch! As the non-COSC versions have been discontinued, you might well have a collector's item there! :thumbup1:Hi and thanks for the welcome, very recently aquired my sub, i'm not yet able to post pics (camera), but promise them to be forthcoming! Mine is a Z series (no COSC rating) and i'm in love with it, funny side note, i attended my girlfriends family get-together this weekend, and noticed her cousin wearing a late 1960's GMT, Said he had been asking his grandfather for it for years, his grandfather finally gave it to him several years ago, he had it serviced with a new dial, crystal and bezel insert (changed it from pepsi to all black) a very beautiful watch indeed! Long story short, I emailed him your website!
