This is a rare opportunity to acquire a One Owner vintage Ploprof with Original Boxes, Papers, and Sales Receipt from 1981.

Very Good Condition. Very few signs of wear, has only a few very light scratches on the case sides and bracelet. Prior to being offered for sale, a certified Omega watchmaker ensured the watch met all factory timekeeping metrics. The crystal and 3 hands were also replaced prior to the watch being offered for sale. The original crystal and hands are included and photographed. Due to the age of the watch, original water resistance metrics could not be met, and it is no longer recommended to use this watch in active water sports.

The reason for replacing the hands was purely functional. It is very common for the original lume in the center of the hands to deteriorate with age which is what happened to the original hour hand.The lume then is at risk of getting into the movement or date window. The original hands are included with purchase.

Watch has been thoroughly checked to insure that all time setting and time keeping functions operate properly.

After four years of extensive testing Omega produced the first generation of the PloProf in the beginning of the seventies. The Compagnie Maritime d’Expertises (short ) and well known professional diver Jaques Cousteau were of help to Omega with developing the firstwaterproof watch designed and built solely for the diving professional. The watch was nicked PloProf, derived from Plongeur Professionnel which is French for Professional Diver.

A major concern with professional dive watches is the entry of helium inside the watch case. Helium is used in diving bells when professional divers have to work at greater depths for a longer period of time. Even if a regular diving watch is able to withstand a certain water pressure, helium molecules still might be able to slowly enter the watch through its gasket materials.
