OMEGA, TITANIUM SEAMASTER DIVER CHRONOMETER WRISWATCH, REF. 277.90.55.21.04.001

Introduced in 1970, the Omega Ploprof is one of the most iconic diver wristwatch. Nicknamed from “PLOngeur PROFessionnel”, the timepiece was bold in terms of design and was considered revolutionary in the way it was conceived and able to respond to the needs of divers. Resulting from approximately four years of research and development, the “Ploprof” relied on an entirely new method of manufacturing, with an ultra-resistant monocoque case made of solid steel. The use of such cases largely reduced the probability of water entry, now made only possible through the sapphire or the crown. In order to counter remaining possibilities of water-entry, the crown was positioned at 9 o’clock for the diver’s ease of wear and the screwed square crown was protected by a large square locking nut. With regards to the crystal, Omega preferred the use of mineral crystal secured in an over-compressed gasket, which is then hidden when the rotating bezel is fixed. To prevent mishandling, the watch was crafted with a red special pusher unlocking the bidirectional bezel.

Retaining the iconic design of the original Ploprof, the present wristwatch is manufactured in a highly attractive grade 5 titanium case and features a blue ceramic bezel with white lacquered dial. It is powered by the Co-Axial Master Chronometer Calibre 8912, known for its anti-magnetic resistance, chronometric performance and precision.
