Omega Goes Ultra Deep With New Planet Ocean Collection

Way back in 2019, Omega revealed their most capable dive watch ever in the Planet Ocean Ultra Deep Professional, and sent it to the 5 deepest points on the planet via Victor Vescovo’s Five Deeps expedition. The watch was an impressive display of tech jammed into a still-kinda-recognizable Planet Ocean that measured 55mm across and 28mm thick capable of keeping its composure under 35,000 feet of water. While it may not have been practical for use outside of the extreme conditions for which it was developed, it featured qualities that many of us would have welcomed on a commercially available Planet Ocean. Today, Omega gives us just that with the Seamaster Planet Ocean Ultra Deep. 

The new supremely capable Planet Ocean watches retain the features (or lack thereof) that made the original so compelling. There’s no date window in sight, the helium release valve has been removed, and the titanium case with manta lug design has been sized down. In addition to the titanium model, a slew of steel examples featuring traditional lugs with a full bracelet are also being made. The new Ultra Deep watches have compromised a bit of their depth rating in the service of a more wearable case. The new watches settle for a mere 6,000 meters, or 20,000 ft depth rating, and in doing so enjoy a trimmer 45.5mm case that measures a tick over 18mm thick. Ok, so the compromises are relative, but it might be best to think of this in a similar manner to that of the PloProf: ridiculous in the best way possible, so it gets a pass on some of the ergonomic concerns.


The Ultra Deep Steel introduces something called O-MEGASTEEL, a “high-performance stainless steel alloy” that is touted by Omega as being stronger, whiter, and shinier than regular steel. These models also get colored gradient dials of blue, burnt orange with orange bezel, and a separate white option with blue bezel. Thanks to their traditional lug design, a bracelet can be used, alongside an optional integrated rubber unit with color matched details. 

The Ultra Deep Titanium gets a matte finish throughout, including a flat gray dial. The manta lug design means you’ll be limited to passthrough style straps, as it’s effectively a fixed lug design. The lug design is organic in its transition to the midcase, not entirely dissimilar to the Tudor FXD, which also features a fixed lug design. Where Tudor went purpose built for shallow executions, Omega has gone to the extreme, and the resulting case dimensions cut a clear contrast to the pros and cons of each approach.

Each of the Ultra Deep Planet Ocean watches utilize Omega’s co-axial master chronometer caliber 8912 that’s been certified by METAS in-house. The 60 hours of reserve will keep you within half a second a day. The closed caseback gets a new etched hippocampus design and all the requisite bona fides labeled around the perimeter. 

The new Planet Ocean Ultra Deep collection is priced from CHF10,400 (~$11,200) for the steel model on a rubber strap, to CHF10,700 (~$11,500) on a bracelet, while the Ultra Deep Titanium can be had for CHF11,400 (~$12,000). No small sum, but if you’re after the extreme, this is as good as it gets. For reference, the Rolex Deepsea Sea-Dweller is rated to 3,900 meters, or 12,800 ft. Omega.
