OMEGA Seamaster Ploprof 1200M White

In 2010 OMEGA added a white version to their popular Ploprof collection of diving watches. It has all of the features professional divers have come to expect from OMEGA: a white bi-directional locking bezel with chrome-coated Arabic numerals, an automatic helium escape valve and water resistance to 1200 metres (4000 feet, 120 bar). The watch, with its timeless white bezel and dial, is presented with either a white rubber strap or a brushed mesh “Sharkproof” bracelet.

The Ploprof’s case cannot be mistaken for that of any other watch: 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.

The Seamaster Ploprof 1200M has a polished, lacquered white dial with an applied polished OMEGA name and logo. The oversized minute hand, which plays such an important role for divers, is crafted from orange anodised aluminium for legibility and is coated with white Super-LumiNova.
