The Omega Seamaster Diver 300M (Ref. 2221.80.00) is a discontinued 41mm stainless steel quartz dive watch produced from the late 2000s to early 2010s. Often called the "Red Seamaster" or second-generation "James Bond" quartz model, it bridges the gap between the classic 1990s ref. 2541.80 and later ceramic-bezel editions.

• Movement. Powered by the rhodium-plated Omega Calibre 1538 precision quartz movement with an end-of-battery-life indicator. According to OMEGA, it runs on a type 371 battery with an approximate battery life of 42 months. [

• Case and Dimensions. Features a 41mm brushed and polished stainless steel case with a 20mm lug width and an approximate total weight of 160g. Its slim profile measures roughly 11.8mm thick, making it notably thinner than modern automatic Seamaster models. 

• Dial ("Red Line" Details). Showcases a deep blue wave-patterned dial distinguished by the "Seamaster" text printed in red just beneath the applied Omega logo. It also upgrades earlier versions with applied white-gold-rimmed luminous hour markers, skeletonized hands with a red-tipped seconds hand, and a framed date window at 3 o'clock.

• Bezel and Crystal. Equipped with a unidirectional rotating bezel fitted with a blue anodized aluminum insert and a domed, scratch-resistant sapphire crystal with internal anti-reflective treatment. 

• Diving Features. Rated to 300 meters (1,000 feet) of water resistance with a screw-in crown, a manual helium escape valve at 10 o'clock, and a 5-link stainless steel bracelet featuring a push-button clasp with an integrated diver's extension.
