What it is:
Your average dive watch has a water-resistance of 300m, which is already way, way deeper in the water than recreational scuba divers will ever go. Last month, Omega revealed a new timepiece that makes those other watches seem like they’re made for the kiddy pool: The Seamaster Planet Ocean Ultra Deep can go 6,000m into the water. It builds on the innovations of the earlier Ultra Deep prototype watches, three of which accompanied explorer Victor Vescovo on a trip to the bottom of the Mariana Trench in the Pacific Ocean in 2019. Vescovo’s submersible reached a depth of 10,935m — the deepest any human, or watch, has ever gone.
How it works:
The seven-piece new collection includes one made from sandblasted grade 5 titanium and six made with the brand’s new steel alloy, rather amusingly called O-megasteel. Measuring 45.5mm in diameter and 18.12mm in thickness, the Ultra Deep’s case is asymmetrical with “Manta” lugs that are fully integrated into the casebody and left open to allow for some flex at extreme depths. Taking inspiration from the load-bearing viewport construction of deep-sea submersibles, the watch features a domed sapphire crystal that is made using a process called EFG (edge-defined film-fed growth). This ensures that the crystal is free from imperfections that might result in shattering when under great pressure. For the six steel models, the new O-megasteel alloy is apparently stronger, shinier with a whiter hue, and more corrosion-resistant than regular stainless steel.
How it looks:
At 45.5mm across and 18.12mm in height, this is not a small watch, but it’s hardly the biggest one that we have seen either — and hey, how many of those larger timepieces are hardy enough to be dropped 6,000m into the sea? Our favourite model is the titanium version, with its cool, matte sandblasted finish. In this model, the same grade 5 titanium is also used for the unidirectional bezel, caseback and crown. The bezel insert is made from brushed black ceramic with a Liquidmetal diving scale. However, a limitation of the titanium model is that it comes only with a Nato strap; metal bracelets or rubber straps are offered only for the steel variants.
