Omega has always been driven by a pioneering spirit; in fact, no watch company in the world holds more records for accuracy. Their watches have been the timepiece of choice for some of history’s greatest explorers—from deep-sea divers to astronauts. 

We will consider the Ultra Deep in the most literal sense of its name: when you are prepared to travel beyond deep, this is the watch you want upon your wrist.

This is a commercial version built on the DNA of Omega's record-breaking Ultra Deep timepiece, which made history by descending to the deepest place on Earth—the Mariana Trench—in 2019. The commercial version features an astounding 6,000 m / 600 atm water resistance, which makes it one of the toughest diving watches on the market.

The bold unidirectionally rotating polished blue ceramic bezel with luminous dot and dive scale in white enamel is easy to read. So too are the 18K white gold hands and hour markers—which are all bathed in SuperLuminova for quick and efficient viewing in low light.

The bright white dial has Arabic numerals at 12, 3, 6, and 9, and the broad arrow-tipped hour and minute hands catch the eye as only Omega hands can do.

You will find the solid caseback in Grade 5 titanium and laser-engraved with the Sonar emblem and iconic Omega Seahorse.

The formidable O-MEGASTEEL case measures 45.5 mm in diameter, 18.12 mm in height, and rests upon an O-MEGASTEEL bracelet with Omega’s patented extendable foldover rack-and-pusher with length adjustment and extra diver extension. Additional features include a screw-down winding crown and scratch-resistant sapphire crystal.

The self-winding automatic Omega 8912 caliber delivers certified Co-Axial Master Chronometer accuracy with 60 hours of power.

From its astounding capabilities as an expert dive piece to its bold and rugged construction with chronometer accuracy, this Omega Seamaster Planet Ocean 6000M Ultra Deep will make an essential addition to your collection.

Standout feature(s): Astounding 6,000 m / 600 atm water resistance; Co-Axial Master Chronometer accuracy with 60 hours of power; rugged ceramic bezel and O-MEGASTEEL case; Grade 5 titanium laser-engraved caseback.
