Omega Seamaster Planet Ocean 600M Co-Axial 42 Titanium Blue Dial

Reference 232.90.42.21.03.001 belongs to the early ceramic generation of the Seamaster Planet Ocean, introduced in 2013 and produced through 2016. Omega executed this version in titanium, pairing the 42mm case with a matching blue dial and a blue ceramic bezel that uses Liquidmetal for the diving scale, a material combination that marked an important step in the brand's modern dive-watch development. Inside is Omega caliber 8500, the in-house automatic co-axial movement that helped define the company's shift away from outsourced calibers in this period. The twin-barrel architecture delivers a 60-hour power reserve, while the free-sprung balance and co-axial escapement underscore the technical priorities Omega was pursuing across the Seamaster line at the time. Collectors tend to notice the balance of utility and refinement here: a full titanium case and bracelet for reduced weight, an exhibition back, and a glossy blue dial that gives the watch a more contemporary character than the earlier black and orange Planet Ocean references. At 600 meters of water resistance, this reference sits firmly within the professional end of the Seamaster range, but the execution is more nuanced than a purely instrumental diver. The 42mm format is also significant, offering a more restrained alternative to the larger Planet Ocean cases that often dominate the category. This is not a limited edition, nor was it made for a specific country or boutique, which makes the appeal of the reference rest where it should, on materials, movement, and execution. For a buyer focused on Omega's mid-2010s technical progression, this reference captures the moment when the Planet Ocean became both more advanced and more wearable. Excellent Condition with Omega box and papers dated 2015.
