Developed in conjunction with Comex and the Jacques Cousteau, Omega launched its first waterproof watch designed and built solely for the professional divers in 1970. . Featured here is a Seamaster 600, nicknamed PloProf (short for Professional Diver in French), it has its crown at 9 o'clock so that the red pusher is more accessible and the relatively cumbersome crown guard does not interfere with wrist movement, made perfect for a diver to adjust the bezel for accurate timing. . One of the most iconic timepieces in sports watch history, the present lot will be offered in the Watches Online sale opening from 26 Nov – 6 Dec. . #Omega #Omegawatches #diverwatch #waterproofwatch #sothebyswatches
