Omega rebuilds the Planet Ocean around a slimmer angular case

The black fourth-generation Planet Ocean returns to 42mm, loses the date and cuts more than two millimetres from its predecessor.

What to know

Reference 217.30.42.21.01.001 represents the most restrained version of Omega’s fourth-generation Planet Ocean. The redesigned 42mm steel case uses sharper surfaces, a flat sapphire crystal and a titanium inner ring, reducing thickness to about 13.8mm while retaining the collection’s 600-metre water resistance.

Its matte-black no-date dial uses rhodium-plated openworked numerals, broad arrow hands and Super-LumiNova. Automatic Master Chronometer Calibre 8912 provides a jumping-hour time-zone function and 60 hours of reserve. The integrated three-link steel bracelet includes six-position adjustment and a diving extension, completing a substantial structural rethink rather than a simple colour update.
