The Omega Seamaster, a popular watch, has a long history dating back to 1948. It was first introduced in 1948 as a tribute to Omega's 100th anniversary and became the brand's best seller. The Seamaster was modeled after waterproof wristwatches worn by the British military during World War II. Its O-ring gasket improved its water-resistance, making it resistant to temperatures up to 60 meters. In 1957, Omega introduced the Seamaster 300, designed for underwater use, but only capable of diving to 200 meters. Oceanographer Jacques Cousteau's team wore the watch during their Conshelf II experiments in the Red Sea.
By the mid-1990s, the Seamaster had fallen out of popularity, but it was selected as the James Bond watch. Pierce Brosnan wore an Omega Seamaster 300 in the film Golden Eye in 1995, and Daniel Craig wore an Omega Seamaster 300 and Planet Ocean in Casino Royale, Quantum of Solace, and Skyfall. In 2015, Omega released the special edition Seamaster 300 Spectre, harking back to the original Bond Seamaster.
