This diver ’ s watch is a very rare lefthanded version from the 1970s . The watch features a bi-directional bezel that can be adjusted and locked by a red push button in the band on the right . The crown is furthermore protected with a locking nut , and the ‘ square ’ is actually a crown .
Reference 166.0077 was made in conjunction with COMEX and Jacques Cousteau , the legendary French naval officer , explorer and conservationist . The watch was used for dive explorations , most notably for oil research . Divers lovingly dubbed the watch ‘ PloProf ’, a shortened name for Plongeur Professionnel . The development and testing for this watch underwent four years before the ‘ PloProf ’ was launched in 1970 . At the time of its launch , the model was among Omega ’ s more expensive watches . Research suggests that the watch retailed for CHF 720 on Milanese bracelet , making this model quite rare today .
