2023 Omega Seamaster Planet Ocean Summer Blue 39.5mm

Here we have a 2023 Omega Seamaster Planet Ocean "Summer Blue," a striking commemorative edition released to celebrate the 75th anniversary of the Seamaster line. Its 39.5mm stainless steel case features the collection's signature lyre-style lugs with a blend of brushed and polished finishes, a 14mm thickness, and a compact lug-to-lug length of 45mm, ensuring a robust yet wearable presence. A blue ceramic unidirectional bezel with a light blue Grand Feu enamel diving scale surrounds the dial, while a helium escape valve sits at 10 o’clock. On the right side is a screw-down signed crown, helping to achieve a professional 600m water resistance. A domed scratch-resistant sapphire crystal protects a unique "Summer Blue" PVD dial, treated with a vertical-brushed finish and a gradient lacquer that darkens towards the outer edge, mirroring the depths of the ocean. It features applied light-blue indices and broad-arrow hands, all coated with a unique light-blue Super-LumiNova, along with a discreet date window at 3 o'clock. On the reverse, the commemorative case back features a stamped Seamaster logo depicting Poseidon with his trident and two seahorses—the original 1956 design and the brand’s current interpretation. Inside, the automatic Omega Calibre 8800 is a Master Chronometer-certified by METAS, resistant to magnetic fields up to 15,000 gauss, and features a Co-Axial escapement and a silicon balance spring. The movement provides a 55-hour power reserve and is finished with rhodium-plated bridges and Geneva waves in arabesque. It comes paired with its original 19mm stainless steel bracelet with a patented extendable foldover rack-and-pusher clasp. The watch is accompanied by its special edition Omega presentation box, swing tag, and full documentation.

This watch is sold with its original Omega box and paperwork. It comes paired with its original 19mm stainless steel bracelet with a patented extendable foldover rack-and-pusher clasp; all links are included. The watch is from August 2023 and is sold in worn condition, but overall it is in very fair condition, as you can see from the photos. A full case and bracelet refurb can be provided at an extra cost on request. The watch comes with our 12-Months Warranty.

Anniversary pieces can sometimes feel a bit forced, but this Omega “Summer Blue” Planet Ocean manages to knock it out of the park. At its core, it’s still very much a Planet Ocean, an absolute tool on the wrist. The 39.5mm case is a sweet spot too—compact enough to wear comfortably, but with enough depth and presence to remind you this is a serious dive watch. The 600m water resistance, helium valve, and that ceramic bezel aren’t just for show. If you have been after a serious tool that still looks effortless on the wrist, this is the watch for your collection!

Formerly known as the La Generale Watch Co., founded in 1848 by Louis Brandt in La Chaux-de-Fonds. When he died in 1879, his sons carried on his dream. In 1880, they moved to 96 Rue Jakob-Stampfli, where they remain today. The brothers produced their first mass-produced calibre, the Labrador, in 1885. Just a few years later, in 1892, they produced the first minute-repeater. In 1903, they renamed the company Omega until 1982, when they officially changed their name to Omega SA. During WW1, Omega watches were used as official timekeepers for the Royal Flying Corps and the US Army. In 1930, Omega and Tissot merged together to form Société Suisse pour l'Industrie Horlogère (SSIH). In 1931, another group was formed - Allgemeine Schweizerische Uhrenindustrie AG (ASUAG). Where SSIH was primarily French-speaking, ASUAG was founded by the more German-speaking members of the Swiss watch industry. In 1948, they introduced the first edition of one of its most symbolic watches: the Seamaster. Omega first introduced the Constellation in 1952. At the time, it was Omega's flagship timepiece. The first models had a Cal. 354 bumper movement in them. Later in 1955, Omega introduced the Automatic Cal. 50x, followed in 1959 by the Cal. 55x (no date) and 56x (date) versions. Many of the Constellations came with pie-pan dials, diamond indexes, and fancy lug configurations. All the gold Constellations of that time have the Observatory of Geneva hand-engraved on the back. The stainless steel and stainless steel/gold versions had a gold medallion on the back with the Observatory of Geneva. The eight stars above the Observatory stand for the many exploits of Omega in the world Chronometer competition. Celebrating the fact that all Constellations are Chronometer Certified. In 1962, when astronaut Wally Schirra wore a Speedmaster on his Mercury Sigma 7 Mission, making it the first Omega watch to enter space. After rigorous tests, NASA used Omega for all their Apollo missions, including the 1969 Moon landing of Apollo 11. Today, Omega is still an astronaut's first choice. In 1969, President Nixon famously said it was “too valuable” and turned down the first-ever all-gold Speedmaster Professional Deluxe. As a response to the ever-growing threat of electronic watches to the manufacturers of mechanical watches, Omega and many Swiss brands, such as Rolex and Patek Philippe, formed Centre Electronique Horloger (CEH). Prototypes began to appear in 1967, with their production starting in 1968. Then, in 1972, Omega introduced the reference, 198.030, which included the Omega calibre 1250, a ‘tuning-fork electronic movement which was made under licence from Bulova. Later, we saw a merger of SSIH and ASUAG into SMH, or Société de Microélectronique et d’Horlogerie. This merger took place in 1983. In 1992, the company acquired Blancpain, and in 1998, they officially rebranded themselves from SMH to the Swatch Group. Then, in 1999, they purchased and integrated Breguet into the Swatch Group.
