The bridges are finished with spiral Cotes Arabesque damascening that Omega applies to all its high-end movements. While the longevity of rubber is a concern – the material doesn’t have the robustness of ceramic for instance – Omega states with certainty that the rubber inlaid bezel has been age tested to the equivalent of years and years with no visible wear. On the Sedna gold model the insert features matching Sedna gold markings pressed into the bezel, while on the black model the markings are Liquidmetal, an amorphous metal alloy with a glass-like atomic structure.Īnd on the blue and red models, the Liquidmetal markings are joined by injected rubber to match the dial. In addition, the bezel is also ceramic with a matching ceramic insert. The screw-down back also operates like a bayonet lock, so the Omega logo and lettering are always correctly aligned and read horizontally. Both the back and case feature large, wave-like teeth that lock against each other when the back is tightened, compressing the rubber gasket in-between to ensure water-resistance. The reason for that is that the hardness and brittleness of ceramic means that the material tends to crack when force is exerted, making a screw-down back a no-go.īut the particular ceramic Omega uses for the Deep Black is slightly elastic, making the Naiad Lock screw-down back possible. Typically case backs of ceramic watches are either ceramic and secured with adhesive, essentially glued onto the case, or made of metal and then screwed into a metal tube inside the ceramic case. “ZrO2” is the chemical formula for zirconium dioxide, the type of ceramic used in the Deep Black. This is the first wristwatch with a screw-down back made of ceramic that screws into a ceramic case, a feature Omega has named Naiad Lock, after the water nymphs in Greek mythology. The latter is significantly more attractive, given the contrast between the two surface finishes, especially the polished bevel along the length of the lugs.īut more interesting than the case material is the case back, which is screw-down. The case finishing is entirely brushed and matte on the red and blue versions of the Deep Black, but alternates between brushed and mirror polished on the rose gold and black models. The style is typical of Omega, with “lyre” lugs that are fortunately short, allowing it to fit on smaller wrists. Made entirely of precisely finished black ceramic, the Deep Black case is large and hefty, being 45.5mm in diameter. The top of the line is the Deep Black with accents in 18k Sedna gold, Omega’s proprietary red gold alloy that does not fade over time. The other three are all ceramic, with various colour accents, and priced the same. The Seamaster Planet Ocean Deep Black combines all of those innovations in a single watch, resulting in an impressively featured, albeit pricey, timepiece.įour versions of the Deep Black are available, all sharing the same fundamental features. Over the last decade Omega has steadily developed new features to improve its watches, ranging from the Co-Axial escapement deep inside the movement to the ceramic case that made its debut on the Speedmaster Dark Side of the Moon. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).Facebook Linkedin Twitter Pinterest Weibo Mail Instagram Other features include an alveol pattern on the screw-in caseback and a black rubber strap with contrasting stitching and an anti-bacterial treatment on the lining. The Planet Ocean “Deep Black” is water-resistant to 60 bar and is driven by the OMEGA Master Chronometer calibre 8906. This has been achieved through OMEGA’s new and patented ceramic Naiad Lock. The hands are 18K white gold and are coated in white Super-LumiNova. In another first, OMEGA has created an oriented screw-in caseback so that the engraved wording sits pleasingly in position. It is coloured totally black to represent the ocean at a depth of 300 m. The glossy and brushed casebody has been crafted from a single block of ceramic, the same material used for the unidirectional bezel and the dial with Arabic numerals.Ī new GMT ring has also been fixed on the dial while the diving scale and OMEGA logo on the crown have been decorated with Liquidmetal™. Exploring the dark side of the ocean, OMEGA has evolved its ceramic expertise to produce the Seamaster Planet Ocean “Deep Black”. This remarkable 45.5 mm timepiece is the combination of a GMT model and a diving watch.
