Very cool, the Doxa 300T professional is high on my list of wants and has been for some time but just now starting to break into the more bespoke side of the watch market. Just popped on a Zodiac SSW 53 Skin and am enjoying that quite a bit. As far as automatics, I'm still rotating a Vostok Scuba Dude on a orange tropical band as an option. Very cool watch and enjoy it! Currently when I'm Overlanding, I can guarantee you'll find me wearing my Sangin Professional with dive bezel.
Beautiful watch! I used to be a PADI certified diver but that was many, many years ago. I didn't own a dive watch back then but if I was diving now, this is the watch I would own. For those that don't dive and just want the look, Seestern makes a really nice homage of this watch.
