OMEGA Seamaster Planet Ocean 600M 43.5mm Watch 215.32.44.21.01.001

The OMEGA Seamaster Planet Ocean 600M 43.5mm (Ref. 215.32.44.21.01.001) delivers serious diving capability in a package that doesn’t compromise on materials or movement technology. The black ceramic bezel with orange rubber accents represents OMEGA’s most advanced bezel construction, while the 600m water resistance puts this firmly in professional diving territory rather than lifestyle sports watch category.

At 43.5mm with 16.09mm thickness, this is substantial without being cartoonish. Appropriate sizing for a watch rated to 200 bar. The ceramic dial and bezel offer genuine scratch resistance advantages over steel alternatives, while the orange rubber elements provide high-visibility contrast useful in low-light diving conditions. The helium escape valve confirms this is built for saturation diving, not just recreational use.

The Master Chronometer Calibre 8900 delivers 60-hour power reserve, 15,000 gauss magnetic resistance, and METAS certification. All technical advantages that matter in demanding environments. The time zone function adds practical utility for international diving operations or travel, while the transparent caseback lets you appreciate the movement finishing.

The structured rubber strap with orange stitching maintains the high-visibility theme and offers genuine comfort advantages over steel bracelets during extended underwater work. The 21mm lug width accommodates serious diving straps if needed.

This Planet Ocean suits buyers who need legitimate deep-diving capability with luxury finishing. It’s discontinued now, adding collectability to genuine professional functionality. Unlike recreational dive watches that prioritise aesthetics, this delivers the materials technology and water resistance for serious underwater work while maintaining the refinement expected from OMEGA’s top-tier offerings.
