Oceaneva has built its latest tool watch around a simple but unusual combination.
The Dodeca-Trench is a serious deep-diving watch with 6,000m water resistance, yet it also carries a true GMT movement and a 24-hour bezel for travellers.
It’s not a discreet watch, but that’s rather the point.

At a glance
- Oceaneva has introduced the Dodeca-Trench, a Grade 5 titanium GMT dive watch rated to 6,000m.
- It combines a 44mm case, 6mm domed sapphire crystal, ceramic 24-hour bezel and Miyota 9075 automatic true GMT movement.
- The watch is limited to 50 pieces per dial colour, with a pre-order price of £605 and standard price of £3,024.
A titanium case built for extreme depth
The Dodeca-Trench starts with a case that makes no attempt to hide its purpose.
At 44mm in diameter and 18.95mm thick, it’s a large watch by any normal measure, but those proportions are tied directly to its claimed 6,000m water resistance.
Deep-water resistance depends on a case’s ability to withstand pressure without deforming, and Oceaneva has given the watch substantial dimensions along with a 6mm-thick domed sapphire crystal.

The use of Grade 5 titanium is what keeps the idea wearable rather than merely theoretical.
Titanium is listed as 45 percent lighter than steel, and its strength-to-density advantage makes sense here given the scale of the case.
The metal also gives the watch a darker grey tone, with brushed finishing adding to its utilitarian character.

Wave dials, ceramic bezel and GMT function
Oceaneva is offering the Dodeca-Trench with a horizontal wave-textured dial in ten colours.
The choices are orange, red, mint, salmon, blue, yellow, white, black, purple and green.
Each version uses black or grey triangular hour markers with lume, paired with matching central hour, minute and seconds hands.
The GMT hand is set apart in a third colour, making the second-time-zone indication easier to pick up at a glance.
That hand works with the bi-directional rotating 24-hour bezel, which uses a black ceramic insert.
The result is a watch that doesn’t treat travel timing as a token add-on, even though the headline specification remains the depth rating.
A true GMT calibre inside a deep-diving shell
Inside the Dodeca-Trench is the Miyota 9075 automatic calibre.
This is a true GMT movement, meaning the 12-hour hand can be adjusted independently from the rest of the display.
For travel, that lets the wearer move the local hour hand when crossing time zones without stopping the watch or resetting the full time display.
It’s a practical choice for a watch that’s presented as an all-purpose tool rather than a dive-only instrument.

The Dodeca-Trench will appeal to buyers who like their tool watches unapologetically engineered, visibly technical and priced around specification rather than understatement.
For anyone drawn to deep-diving excess but unwilling to give up the everyday usefulness of a traveller’s GMT, Oceaneva has put together a notably unusual mix.
