OMEGA Seamaster Ploprof 1200M 55 x (Summer Blue)

Omega's Seamaster Ploprof 1200M 55 x (Summer Blue), reference 227.32.55.21.03.001, is a dive watch with a 55 mm steel case. It measures 15.5 mm thick with a 45 mm lug-to-lug span, and the bidirectional rotating bezel sits under a flat sapphire crystal treated with anti-reflective coating on both sides. The blue dial is driven by the self-winding calibre 8912, a Co-Axial Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, with a 60-hour power reserve. A helium valve and screw-down crown support serious depth work, and the movement carries a time zone function. The case rides on a blue rubber strap with a steel pin buckle. Water resistance reaches 1200 metres.
