Review: Omega Seamaster Planet Ocean Ultra Deep

In 2019, American adventurer Victor Vescovo established a world record for the deepest dive achieving a depth of 10,935 metres / 35,876 feet. During a 12-hour mission, he piloted his submersible to the bottom of the Mariana Trench, the deepest point on planet Earth.

Perfectly performing at such impressive depth thanks to waterproofness up to a pressure of 1,500 bar (15,000 metres / 49,212 feet), three OmegaSeamaster Planet Ocean Ultra Deep Professional timepieces made the dive with him. Each watch confirmed Master Chronometer certification even after the extreme underwater journey (more on this exceptional achievement here).

Based on the same innovative technologies and design optimizations, last March Omega introduced the new Omega Seamaster Planet Ocean Ultra Deep collection, initially comprised of one model in titanium and six models in stainless steel (you can read the product line overview here).

We had the possibility to put our hands on two of these hi-performance diver's watches, the one in titanium and one of the steel references, and we are now glad to share our pictures and report with our readers.

Whether in titanium or in steel, the new Planet Ocean Ultra Deep has a striking look with its imposing case, large bezel and colourful dial. Measuring 45.5 mm x 18.12 mm, it guarantees water-resistance up to a pressure of 600 bar (approximately 6,000 metres / 20,000 feet).

The first Planet Ocean Ultra Deep model is crafted from a Grade 5 titanium alloy (titanium, aluminium and vanadium) that is much lighter and more hard-wearing than steel while also offering a brighter appearance compared to Grade 2 titanium.

Featuring a brushed ceramic insert enriched by a Liquidmetal diving scale, the unidirectional counter-clockwise bezel rotates very precisely thanks to its 120 smooth clicks.

Fully integrated into the titanium casebody, the typical “Manta" lugs are left open to lower the risk of exceeding material limitations at full ocean depth, as both the watch and the strap can be subjected to high traction loads.

These lugs support a striped NATO strap, in cyan and black, made from polyamide yarn sourced from 100% recycled fishing nets and secured to the wrist with a loop and buckle in grade 5 Titanium.

The black ceramised titanium dial offers the ideal contrast to make the 18k white gold hours markers and Broad Arrow hands stand out.

The cyan numerals, the Seamaster and Ultra Deep logos as well as the central seconds hand with white-to-cyan gradient add a nice touch to the ensemble.

The second Planet Ocean Ultra Deep model featured in our review is made in O-MEGASTEEL, a brand new stainless steel alloy that offers superior strength and corrosion-resistance, whiter colour and exceptional shine. Like the titanium model, also this steel model features the new crown guards for improved protection.

Anti-reflective on both sides, the domed sapphire crystal protects a lacquered gray-to-black gradient dial that is complemented by four Arabic numerals in a striking orange that matches the colour of the polished ceramic bezel.

For improved readability in darker environments, the hands, the hour markers and the bezel's diving scale are coated with white Super-LumiNova that glows in blue, except for the bezel's dot and the minute hand which stand out for their green colour.

This steel model can be equipped with an O-MEGASTEEL bracelet featuring a patented extendable foldover rack-and-pusher with a complementary length adjustment and an extra diver extension or with a technical rubber strap secured to the wrist by an O-MEGASTEEL buckle.

All casebacks sport a black laser-engraved Sonar emblem, with the unmistakeable Omega Seahorse at its centre encircled by the words “Diver’s watch 6000 m for saturation diving”.

The watches are driven by the Co-Axial Master Chronometer Calibre 8912, a state-of-the-art movement that beats at the frequency of 3.5 Hz (25,200 vibrations per hour) and guarantees at least 60 hours of power reserve. 

Each Omega Seamaster Planet Ocean Ultra Deep is Master Chronometer certified by the Swiss Federal Institute of Metrology (METAS). In order to earn this distinction, the finished watches - not just the movement - are tested for their precision, during and after exposure to magnetic fields greater than 15,000 Gauss, for autonomy and for water resistance. The exceptional performance in terms of resistance to magnetic fields is possible thanks to the free sprung-balance with silicon balance spring equipping the movements.

Maybe not all wrists can carry a diver's watch like this due to its size but those who can will certainly experience great feelings while wearing it. The titanium version is still pretty light considering its volume while the steel model, especially when matched to its steel bracelet, will definitely make happy those who prefer to feel some weight on their wrists. As a reference, the wrist in our pictures is 17.7 cm / 7 in.
