OMEGA Seamaster Planet Ocean 600M Chronograph Watch 215.32.46.51.06.001

The OMEGA Seamaster Planet Ocean 600M Chronograph 45.5mm (Ref. 215.32.46.51.06.001) delivers extreme diving capability with legitimate chronograph functionality for underwater timing operations. The 600m water resistance places this in commercial saturation diving territory, whilst the helium escape valve addresses the specific challenges of prolonged deep-sea operations where helium infiltration becomes a real concern.

At 45.5mm with 19mm thickness, this provides substantial presence appropriate for extreme diving equipment whilst housing the complex chronograph movement and achieving extraordinary water resistance. The green ceramic bezel with Liquidmetal™ scale ensures permanent legibility through a revolutionary bonding process that prevents chipping or separation of the diving scale markings.

The Master Chronometer Calibre 9900 delivers METAS certification with 15,000 gauss magnetic resistance and column wheel chronograph construction. The innovative single subdial consolidates 60-minute and 12-hour counters for intuitive elapsed time reading, eliminating the confusion of multiple subdials during underwater operations. The Co-Axial escapement and silicon balance spring provide enhanced long-term reliability.

The integrated green rubber strap with structured pattern offers genuine advantages for diving use including rapid drying, chemical resistance, and comfort during extended underwater work. The extendable clasp accommodates varying wetsuit thickness without tools.

This Planet Ocean Chronograph suits buyers who need extreme diving capability with timing functionality for professional underwater operations. The 600m rating serves commercial diving, offshore construction, and technical diving where conventional dive watches reach their limits. The chronograph enables precise timing for decompression stops, dive planning, and underwater work procedures whilst maintaining the water resistance that extreme diving demands.
