Created as the most reliable timepiece for professional divers, the initial Proplof-the Seamaster 600m was released in 1970. And a new updated version of the legendary Seamaster Ploprof was just introduced at Baselworld 2010. The new Ploprof with white dial and white rubber strap, I would like to call it a white version of Ploprof. Royal to its original, it looks almost the same in the appearance with its ancestors. But I would say Ploprof looks more elegant and beautiful in white version, as you can see the pictures.

This Omega Seamaster Ploprof measures 55mm wide. This great size will be inconvenience for daily wearing, but that is what a professional diving watch needs to be legible. What’s more, to ensure perfect legibility udenerwater, the oversized minute hand is crafted from orange anodized aluminium and coated with white SuperLumiNova. Instead of a steel strap, rubber strap will be more practical and comfortable in diving events.

As a professional diving watch, it has all cutting-edge technologies that you expect from Omega. Ticking inside the watch is the Omega 8500 Calibre. The self-winding movement with Co-Axial Escapement for greater precision stability and durability has free sprung-balance, 2 barrels mounted in series, automatic winding in both directions to reduce winding time. And the visible bridges and the oscillating mass are decorated with exclusive Geneva waves in arabesque. The Power reserve is 60 hours.

The screwed-in crown is located at 9 o’clock under a protective buffer. Its unique positioning allows freer wrist movement and prevents any inadvertent manipulation. At the 2 o’clock position is the Ploprof’s characteristic bezel-release security pusher with an orange anodised aluminium ring. Pressing the pusher allows the bezel to be rotated in either direction and then locked firmly in position, ensuring that it cannot be accidentally shifted during a dive. The Ploprof has an automatic helium escape valve located on the side of the case at the 4 o’clock position. This feature allows helium atoms to escape during decompression, and is particularly useful for professional divers operating from diving bells.
