Omega Planet Ocean 600M 37.5mm Steel/Diamond Black Dial Leather Strap 232.18.38.20.01.001

The Omega Planet Ocean 600M is one of the most respected names in the dive-watch universe, tracing its lineage back to Omega's long association with underwater exploration and professional diving. Launched in the mid-2000s as a spiritual successor to the original Seamaster 600 worn by professional divers, the Planet Ocean distinguished itself with a larger, bolder case, a helium escape valve, and Omega's then-revolutionary Co-Axial escapement — setting a new benchmark for what a modern luxury dive watch could be.

Reference 232.18.38.20.01.001 represents the 37.5mm expression of the Planet Ocean 600M family, a size that broadens the collection's appeal without sacrificing any of its core identity. The 37.5mm stainless steel case retains the Planet Ocean's characteristic broad lugs, pronounced crown guards, and the screw-in crown that contributes to its impressive 600-metre water resistance rating — a specification that speaks to genuine dive capability, not mere aesthetic pretension.

The black dial is dressed with both index and Arabic numeral hour markers, a signature detail of the Planet Ocean that nods to the collection's professional timing roots while keeping legibility front and center. The most glamorous element of this reference, however, is its diamond-set bezel, which replaces the standard ceramic or aluminum dive bezel with a continuous ribbon of brilliant-cut diamonds. This contrast — hardened dive-watch architecture paired with precious gem-setting — is precisely what defines this variant as a crossover piece of rare sophistication.

Powering the watch is Omega's Co-Axial movement, a technology developed in partnership with the late independent watchmaker George Daniels. The Co-Axial escapement dramatically reduces sliding friction between escape wheel and pallet, resulting in improved long-term accuracy and extended service intervals compared with traditional Swiss lever escapements. In a brand-new example such as this, buyers receive the full benefit of Omega's factory-fresh tolerances and official warranty coverage.

The leather strap softens the overall aesthetic and reinforces the dual nature of this reference: it is a dive watch you can wear with a suit.
