This circa 1969 dive watch is an uncommon find. This particular Doxa Sub 300T Sharkhunter was worn and used regularly as a dive watch by its owner. The robust 43.5mm. stainless steel screw-back case has NEVER been polished and retains ever little nick and bump…I LOVE THAT! The dial and hands are original. Only the seconds hand has been re-lumed as only can be noticed under ultraviolet light. This black dial is hard to find and is the shade utilized by Jacques Cousteau for deep diving, as black was more visible in deep water. Orange was better for shallow. The manual winding ETA for Doxa movement was just serviced and is accurate. This watch came with its expensive vintage rubber tropic strap and correct steel buckle. This true tool watch by Doxa is a real collector’s piece. I highly recommend this watch.
