The story behind this Omega Seamaster Planet Ocean Ultra Deep
Omega has a well-documented technical history in underwater exploration. In 2019, the manufacturer equipped a submersible for a dive to the deepest point of the Mariana Trench. This Seamaster Planet Ocean Ultra Deep, reference 215.30.46.21.06.001, stems directly from this experiment. It offers certified water resistance for saturation diving without the need for a helium escape valve. The overall architecture of the case has been specifically developed to withstand extreme pressure whilst maintaining proportions that are comfortable on the wrist.
Case, calibre and strap of this Seamaster Planet Ocean Ultra Deep
The case measures 45.5 mm in diameter and is machined from O-MEGASTEEL, an alloy offering increased structural strength compared to traditional steel. The rotating bezel features a matt orange ceramic insert. The dial features a gradient background ranging from a light grey centre to an opaque black outer edge. The hours are indicated by raised hour markers and orange Arabic numerals for easy reading. The watch is powered by the calibre 8912, a Master Chronometer-certified self-winding mechanical movement guaranteeing a 60-hour power reserve. The metal bracelet is fitted with a folding clasp featuring a fine-adjustment system.
Why this Omega watch
This timepiece meets the expectations of collectors seeking a strictly professional diving watch. The omission of the helium escape valve on a model rated to such a depth highlights a high level of expertise in watch engineering. The combination of the orange insert and the grey gradient dial gives it a strong visual identity and a cool aesthetic. This is a technically accomplished model, available second-hand in excellent condition.
