Omega - 224.32.55.21.04.001 Seamaster PloProf Co-Axial Stainless Steel / White

Omega 224.32.55.21.04.001 description

The Ploprof’s case, like that of its predecessor, cannot be mistaken for that of any other watch: the screwed-in crown is located at 9 o’clock under a protective buffer and, as with the original Ploprof, it allows freer wrist movement and prevents unintended manipulation.

The time and date adjustments are made by unscrewing the crown to release the protective buffer and then pulling the crown to the appropriate position. The Co-Axial calibre 8500 makes it possible to adjust the hour hand separately to accommodate different time zones or for the changes to daylight savings and back to standard time.

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 Omega Seamaster Ploprof 1200M bears a strong physical resemblance to its famous ancestor and it carries on the traditions of robust reliability and water resistance which have always defined Omega’s divers’ watches. But there are also some remarkable improvements: for example, the watch is driven by the Omega Co-Axial calibre 8500 with a free sprung balance. This movement, launched in 2007, was created from inception by Omega and is one of the key elements in the revolution in mechanical watchmaking which has been taking place at the company since 1999.
