Founded in La Chaux-de-Fonds in 1848, Omega has built one of the most storied reputations in Swiss watchmaking — as official timekeeper of the Olympic Games, as the watch worn on the Moon during Apollo 11, and as the brand behind James Bond's wrist since 1995. The Seamaster Planet Ocean, introduced in 2005, sits at the top of Omega's dive watch hierarchy — a professional 600-metre instrument built around the brand's Co-Axial movement technology and designed for serious underwater use. The orange-numeral variant is the most immediately recognisable and sought-after configuration in the collection, with a colour accent that has become as iconic as the watch itself.

Reference 232.30.42.21.01.003 is a 42 mm stainless steel automatic diver's watch, 15.5 mm in thickness, with a polished and brushed case and characteristic twisted lugs. The black dial carries applied luminescent stick hour markers alongside broad arrow hands, with orange Arabic numerals at 12, 3, 6 and 9 o'clock adding an unmistakable contrast against the dark background. A date window sits at three o'clock, and a manual helium escape valve is positioned at ten o'clock. At its heart beats the Omega Co-Axial Calibre 8500, an in-house movement running at 25,200 vph with 39 jewels and a 60-hour power reserve, certified as a chronometer and visible through the sapphire exhibition caseback. The domed scratch-resistant sapphire crystal carries anti-reflective coating. The unidirectional rotating bezel features a black ceramic insert with a graduated diving scale. Water resistance is rated to 600 metres. The watch is fitted on a brushed and polished stainless steel bracelet with Omega's glide-adjust deployant clasp.

This Omega Seamaster Planet Ocean 600M Co-Axial is in near mint condition and comes as a full set.
