Oceaneva’s 6000m GMT is a lot of watch, especially from the side

I like a big tool diver, but 18.95 millimeters thick is a lot. The Oceaneva Dodeca-Trench has an interesting combination of a titanium case, a proper traveller GMT movement and a twelve-sided bezel. Then I look at the side view and start wondering how often I would actually choose to wear it.

The green wave dial is the one that catches my eye. The broad hands and large markers suit the case, and the black ceramic bezel gives the whole thing a fairly purposeful look. I can enjoy an oversized piece of diving equipment. I still want the size to feel like part of a watch I want, rather than a specification I have to talk myself into accepting.

A serious set of claimed specifications

Oceaneva lists a 44-millimeter Grade 5 titanium case, 54-millimeter lug-to-lug span and 22-millimeter strap width. The maximum thickness, including the sapphire, is 18.95 millimeters. Titanium is appealing here, but I haven't weighed the watch or worn it. A lighter material doesn't tell us by itself how a case this tall balances on a wrist.

Inside is the automatic Miyota 9075 traveller GMT. The bezel is bidirectional, with 24 clicks and a ceramic insert, so its purpose is time-zone tracking rather than a conventional elapsed-time dive scale. The combination is interesting, especially at the current presale price. I have not tested the movement, bezel action or finishing.

The big headline is Oceaneva's claimed 6,000-meter water resistance. That is the manufacturer's rating, and I haven't independently pressure-tested it. The product page makes several ambitious market-first and material-strength claims as well. I'm not treating those advertising comparisons as established facts. The dimensions and movement already give me plenty to think about without declaring it the best value in watchmaking.

Ten colors, one very substantial family

The current release comprises orange, red, mint, copper/salmon, yellow, blue, white, black, purple and green executions. Oceaneva identifies each with its own reference and says production is limited to 50 of each. They share this model page; the color references remain separate in the variant list below.

The official US brand page lists $799 presale pricing when checked October 31, 2026, alongside a much higher $4,000 regular-price comparison. I'm using the actual $799 offer for the chart. I haven't established that the comparison price reflects normal transaction prices. The brand promises shipment by November 30 and says buyers will be asked to choose a standard or long strap before shipping. Neither statement proves completed fulfillment.

I'm at 68 out of 120 bezel clicks. The green dial and traveller GMT make me interested, but nearly 19 millimeters of height is a major obstacle even with my fairly generous tolerance for tool divers. I would need real wrist time before deciding that the depth rating justifies that much case.
