This Breitling SuperOcean "Slow Moving Chronograph" Diver is the Holy Grail of Breitling Chronographs! Breitling Ref 2005, Circa 1965. A very near mint example of an exceptionally rare, unusually complicated, and super high quality watch. Sold as a diving watch in 1965, the chronograph function displays only the minutes, by way of the large, diamond topped hand. Moving at a "minutes pace", one might not know it was even running. SO... the dial is fitted with a round aperture window above 6:00. When the chrono is engaged, the window goes white. When stopped, a small white dot is displayed, and when reset to zero, goes to black again. It is in near mint condition, never polished, with just a few VERY light scratches and running perfectly.
HERE is a great review of the model from 2009. Given this condition and rarity, it is very conceivable that it is the best example in existence.
