Omega Seamaster Planet Ocean 600M Co-Axial
Founded in 1848 in Biel/Bienne, Switzerland, Omega has earned its place among the most respected names in watchmaking through decades of precision engineering and sporting achievement. The Seamaster Planet Ocean, launched in 2005, is the brand's dedicated professional dive watch — drawing directly on the DNA of the original Seamaster 300 from the late 1950s and built to perform at serious depths.
The Omega Seamaster Planet Ocean 600M, reference 232.30.42.21.01.003, is a well-executed 42 mm stainless steel dive watch with a nicely structured black dial featuring luminescent index hour markers and broad arrow hands, brought to life by bold orange Arabic numerals at 3, 6, 9 and 12 — a detail that gives this variant its unmistakable character. A date window sits at 3 o'clock. At its heart beats the COSC-certified Omega Co-Axial Calibre 8500, a fully in-house developed movement running at 25,200 vph with a power reserve of 60 hours — a movement that enthusiasts will know for its low-friction escapement and long service intervals. A domed scratch-resistant sapphire crystal with anti-reflective coating protects the dial, while the black ceramic unidirectional rotating bezel adds both durability and a refined sporting look. The helium escape valve at 10 o'clock underlines the serious dive credentials. Water resistance is rated at an impressive 600 metres. The movement is visible through a sapphire exhibition caseback. The watch is fitted on a stainless steel bracelet with a deployment clasp.
This Seamaster Planet Ocean is from October 2013, is in good condition with traces of use on the polished parts of the case. Comes as a full set and a full service at Omega in 2019.
