Omega Planet Ocean 600M & De Ville Trésor: The Professional Diver & The Hidden Gem
Two collections that represent the extremes of Omega's range. The Seamaster Planet Ocean 600M is a professional diver rated to 600 meters (6,000 meters in the Ultra Deep variant), with ceramic dial and bezel, helium escape valve, and Master Chronometer Cal. 8900 delivering 60-hour power reserve. The De Ville Tresor is a manually wound dress watch with Master Chronometer Cal. 8910 producing 72-hour power reserve in a 10.6mm case. Planet Ocean steel retails around $8,000; pre-owned runs $5,000 to $6,500. First-generation Cal. 2500 references start at $3,000. The Tresor in steel retails at $7,100; pre-owned sits at $4,500 to $6,000. The Ultra Deep prototype reached 10,928 meters at the Challenger Deep in 2019. Both collections are overshadowed by the Speedmaster and Seamaster 300M and priced accordingly.
Specifications
History
The Planet Ocean launched in 2005 as Omega's answer to the question: what if we built a Seamaster that could actually go deep? Inspired by the Seamaster 300 of the late 1950s but built with modern materials and a 600m depth rating, it immediately established itself as Omega's serious tool diver. The De Ville Trésor traces its name to a 1949 Omega pocket watch, but the modern collection was revived in 2014 as a manual-wind dress watch, a deliberate counterpoint to the brand's increasingly sport-focused catalog. The Trésor (French for 'treasure') was positioned as the hidden gem of the lineup, a watch for connoisseurs who valued restraint over specification sheets.

Market Trajectory
Planet Ocean: steady and mature: this is a well-understood collection with predictable pricing. Ultra Deep: niche but stable. Trésor: undervalued and largely undiscovered by the broader market: potential for upside if dress watches cycle back into fashion.

Best Value Pick
Planet Ocean: first-gen ref. 2200.50.00 at $3,000-$4,500, the original 600m diver with Co-Axial movement. Trésor: steel 40mm at $4,500-$6,000, a Master Chronometer manual-wind dress watch at an absurdly good price.

Collector's Lore
The Planet Ocean has always lived in the Seamaster 300M's shadow despite being the objectively more capable dive watch. Enthusiasts call it 'the Omega that should be more famous': 600m depth rating, ceramic everything, Master Chronometer certified, and it was literally Bond's watch when Daniel Craig rebooted the franchise. The Ultra Deep story is genuinely extraordinary: a prototype strapped to the outside of a submersible at the bottom of the Mariana Trench, still running perfectly after experiencing pressures that would crush a car. The commercial 6,000m version is the most extreme production dive watch from any major brand. The De Ville Trésor is the opposite kind of collector's secret, in a market obsessed with sport watches, Omega quietly makes one of the best manual-wind dress watches in the industry. Forum veterans call it 'the watch Omega doesn't know how to market': brilliant execution, zero hype. In the Diamond District, we see Planet Oceans move steadily and Trésors surprise people who didn't know Omega made anything this elegant.
