OMEGA'S REMARKABLE DIVE INTO THE ABYSS: THE ULTRA DEEP

Limiting Factor


In an unprecedented adventure spanning April to May 2019, The Five Deeps Expedition made history by reaching the deepest point on the planet, the Eastern Pool of Challenger Deep in the Mariana Trench. This feat was achieved by Victor Vescovo, who piloted the Deep Submergence Vehicle (DSV) Limiting Factor, the world's deepest diving operational submersible.

Before embarking on this extraordinary journey, all watches, including the prototypes FOD-X 1 and 2 ("full ocean depth experimental"), underwent rigorous pressure testing at Triton Sub's facility in Barcelona. The chosen maximum pressure equalled the depth of the Mariana Trench. However, OMEGA, in adherence to dive watch standards and to ensure utmost safety, insisted on an additional 25% safety margin. This meant the watches had to perform flawlessly at an astonishing 1500 bar, equivalent to 15,000 meters.

Victor Vescovo attached the prototypes to his Triton-built submersible, securing each one to the vessel's robotic arms. As he descended into the Mariana Trench, an additional Ultra Deep Professional, FOD-X 3, was affixed to one of the three detachable lander vehicles accompanying the dive.

After a four-and-a-half-hour descent, the Limiting Factor touched down on the ocean floor, enduring around 16 tonnes of pressure on the sapphire crystal. Vescovo remained there before ascending, concluding the mission after 12 hours. However, a complication arose: all but one of the three detachable landers returned with him, and the one missing happened to carry FOD-X 3.


Victor Vescovo faced a dilemma: leave the experimental watch at the Mariana Trench's bottom or return to retrieve it. Opting for the latter, planning and waiting for optimal conditions became imperative. Consequently, FOD-X 3 endured an unplanned test, facing the extreme conditions of 16,000 psi at the ocean's deepest part for two and a half days.


When the watch was eventually located, rescued, and brought to the surface, it not only continued to tick but had lost merely one second in time during this unparalleled adventure. OMEGA's watches not only survived the abyss; they emerged with their precision intact, a testament to their durability and the relentless pursuit of excellence in watchmaking.

To certify the OMEGA Ultra Deep Professional as a diver's watch for saturation diving, it underwent rigorous testing in line with the ISO 6425:2018 standard. Nine distinct tests, spanning visibility, magnetic resistance, temperature cycling, salt spray, shock resistance, water resistance, free-fall shock, resistance of attachments, and saturation diving, were conducted. METAS certification attests that the watch meets all required criteria, ensuring its reliability in the harshest underwater conditions.


The dial of the Ultra Deep Professional intricately mirrors the bottom of the Challenger Deep in the Mariana Trench, the world's deepest point. Mapped by the Five Deeps team with almost one million sonar points, the lacquered finish provides a stunning depth effect. Additionally, shining a UV light unveils the playful message "OMEGA WAS HERE," commemorating the record dive of 10,935 meters and marking the Western, Central, and Eastern Pools of the trench.


Introducing O-MEGASTEEL, a high-performance stainless steel alloy crafted through a sophisticated Pressure Electro Slag Remelting process. This method ensures high purity, allowing for enhanced polish and an unparalleled shine. O-MEGASTEEL, stripped of nickel and enriched with nitrogen and manganese, not only offers a brighter white colour but also boasts superior strength with 40% to 50% higher hardness than conventional steel. Beyond being non-ferromagnetic, this unique composition provides exceptional corrosion resistance for enduring aesthetics.

The display of the Ultra Deep is safeguarded by a distinctive sapphire crystal developed in-house by OMEGA, employing the Edge-defined Film-fed Growth (EFG) process. This technique ensures a defect-free crystal, maximising the unique properties of sapphire. Sapphire plates, grown and cut using the EFG process, are machined and polished to create crystals of extraordinary strength and clarity, ensuring a clear view of the display in all conditions.


Powering the Ultra Deep is the Calibre 8912 self-winding movement with a Co-Axial escapement. Certified as a Master Chronometer by METAS, it resists magnetic fields up to 15,000 gauss. The free-sprung balance with a silicon balance spring, coupled with two barrels mounted in series, facilitates automatic winding in both directions. The time zone function and the special luxury finish with Geneva waves in arabesque complete this engineering marvel, promising precision and durability at unparalleled depths.
