OMEGA Seamaster Planet Ocean 6000M (Ultra Deep)

Omega's Seamaster Planet Ocean 6000M Ultra Deep, reference 215.30.46.21.04.001, is a dive watch with a 45.5 mm steel case. Thickness runs to 18.12 mm and the lug-to-lug measures 51.9 mm, so it wears as a substantial tool watch. A unidirectional rotating bezel surrounds the white dial, and a screw-down crown secures the case. Inside is the self-winding calibre 8912, a Master Chronometer movement certified by METAS with resistance to magnetic fields up to 15,000 gauss and a 60-hour power reserve. The dial sits under a domed sapphire crystal treated with anti-reflective coating on both sides. A steel bracelet with a foldover clasp, comfort setting and diver extension completes the watch. Built for extreme depth, the case carries a water resistance rating of 6000 metres.
