Omega 232.30.44.22.01.002 (Pre-owned - Excellent) — USD 6,499 on eBay

The Omega Seamaster Planet Ocean collection, introduced in 2005, represents Omega's most robust and technically advanced contemporary dive watches, building upon the rich legacy of the Seamaster line. The reference 232.30.44.22.01.002, a Seamaster Planet Ocean 600M GMT, emerged in the 2013-2016 period, expanding the series' utility beyond pure diving with a crucial travel complication. It sits distinctly from the more traditional Seamaster Professional 300M with its iconic Bond heritage and the versatile Aqua Terra, asserting its identity as a serious professional instrument. The 44 mm stainless steel case of the 232.30.44.22.01.002 embodies the Planet Ocean's characteristic thicker profile and substantial presence, designed for serious saturation diving with a water resistance rating of 600 meters. A black dial provides excellent legibility, while the presence of a ceramic bezel, a hallmark of this generation of Planet Ocean models, enhances scratch resistance and aesthetic appeal. The addition of a GMT function differentiates this model, typically manifesting with an additional hand and a 24-hour scale on the bezel or inner flange, making it a highly functional timepiece for global travelers and professionals. Powering the watch is Omega's automatic Caliber 8605, a significant in-house movement featuring Omega's Co-Axial escapement. This advanced escapement, developed by George Daniels, contributes to superior chronometric performance and long-term stability, a key selling point for modern Omega watches. The Caliber 8605 is also a certified chronometer, further underscoring its precision. As part of the evolving Planet Ocean line, this GMT variant holds appeal for collectors seeking a modern Omega diver that combines the brand's professional diving credentials with the practical utility of a second time zone, representing a period of significant in-house movement development and design refinement for the series.
