Initially released in 1948 and based on watches used by airmen in WWII, the Omega Seamaster has become one of Omega’s best-known collections. Initially, a dress-style watch with thick lugs, the Seamaster was designed to promote daily wear while remaining functional for use in water with 62.5 meters of water resistance. However, the modern Seamaster that we know and love today was born nine years later, in 1957. This was when the Seamaster 300 was released after Omega was inspired to upgrade the Seamaster after they had 50 Seamaster cases with rubber O-ring gaskets tested in 1955, which led them to work with new materials and push their boundaries. Inspired by the same desire to build upon the foundations of the Seamaster before it, Omega launched the Planet Ocean sub-collection in 2005 as their ultimate dive watch, of which included the model we have here, the Planet Ocean 600M ref. 2209.50.00. Featuring a 42mm stainless steel case with a black dial boasting orange Arabic numerals at 6, 9 and 12 o’clock to match its orange bezel, this large and imposing timepiece offered exceptional timekeeping no matter the circumstance, be it in the water or on land, as the Seamaster collection has always strived to do since its initial launch all those decades ago.

Watch is in excellent overall condition. Case shows some wear, with marks and scratches visible along the lugs, midcase and bracelet. Caseback has some marks as seen in the images. The bezel insert has very minor signs of wear, with some loss of the orange anodization visible in a few areas. The crystal has some minor scratches along the 9 to 10 o'clock edge. Dial and hands are near-mint. Bracelet has 14 links total, 5 of which are removable. It fits an approx 7 3/4" wrist.

An intensely robust watch created to level up Omega's extreme dive watch offerings, the ref. 2509.50.00 embodies everything the Planet Ocean collection has been about since its debut.
