The Seamaster Planet Ocean 6000M Ultra Deep comes in a 45.5 mm x 18.12 mm diameter case (51.95 lug-to-lug) available in either stainless steel or sandblasted forged grade 5 titanium. All seven Ultra Deep references have robust cases and gaskets to achieve an impressive depth rating of 6,000 meters. Inspired by a submersible viewport, the water resistance of the Ultra Deep is aided by the sapphire crystal’s unique conical (protuberant) load-bearing design. 

Perhaps most interestingly, no helium escape valve is required thanks to the ultra-robust design of the watch case, crystal, gaskets, and so forth.

The highest performance model of the group is made of forged titanium with a brushed ceramic bezel, a black ceramized titanium dial, an asymmetrical case shape, and fixed Manta lugs model has fixed Manta lugs (similar to the Tudor Pelagos FXD Marine Nationale) which are more robust than traditional lug and spring bar configurations, providing an ultra-reliable at keeping your watch secured to your wrist. The titanium Ultra Deep is the closest to the original Ultra Deep, which became the deepest mechanical dive watch record holder in 2019.

The remaining six stainless steel Ultra Deep references, all have ceramic bezels, a symmetrical case shape (not asymmetrical like the titanium model), and traditional lugs with removable spring bars (not Manta lugs like the titanium model). For the stainless steel Ultra Deep models, a new crown guard has been integrated into the watch’s case, which protects it from being inadvertently moved while underwater.

The titanium Ultra Deep reference has a titanium caseback, medallion, and crown — while the six stainless steel references have stainless steel casebacks, with titanium medallions, and stainless steel crown. All of the watches are marked “Divers’ watch 6000 m for saturation diving” which signifies they are compliant with the ISO 6425:2018 standard for saturation divers’ watches.

Driven by the Co-Axial Master Chronometer Calibre 8912, all watches in this collection are Master Chronometer certified at Switzerland’s highest standard of precision, performance, and magnetic resistance.

There are four dial variations: faded black/gray for the full titanium model or lacquered white, blue-black gradient, or gray-black gradient for the stainless steel models. The surface of the dials is glossy and the indices and hands are made with 18K white gold.

While the full titanium model comes with a nylon Nato style strap, the other six references either come with a rubber strap that has a technical diving suit structure on the upper surface, along with a steel buckle, or a steel bracelet with Omega’s patented extendable foldover rack-and-pusher, with a complementary length adjustment and an extra diver extension.

Starting at $11,200 for an Ultra Deep in stainless steel with a rubber strap, the retail price rises to $11,600 on a stainless steel bracelet, and to $12,300 for the titanium Manta lugs equipped watch.
