Unique in Every Way

Used for the entire 41 mm case and buckle, Bronze Gold was specifically developed to produce a pleasing aesthetic and hue, while also offering a bronze alloy that could be worn with direct contact on the skin, thanks to its distinctive composition.

"The colour of Bronze Gold sits exactly between OMEGA’s 18K Moonshine™ gold and 18K Sedna™ gold."

Made to Last Longer

Bronze Gold is a one-of-a-kind alloy enriched with noble elements such as 37.5% gold, hallmarked as 9K, as well as palladium and silver. As well as featuring a soft pink hue, it offers incomparable corrosion resistance without verdigris-oxidation, and will therefore age slowly and retain its natural and beautiful patina over a longer period of time.

Key Features

  • Bronze Dial
    The sandwich dial uses a common bronze alloy (CuSn8) to offer a unique dark brown colour with a patina created after a special aging process. The contrast with the Bronze Gold is therefore particularly captivating!
  • Brown Ceramic Bezel
    To complement the Bronze Gold, the bezel ring of this timepiece has been created in brown ceramic with its diving scale in vintage Super-LumiNova. It is also thinner than previous bezels to give the watch a slimline look.
  • Leather Strap
    Adding to the vintage charm of this timepiece, OMEGA has placed the watch on a brown leather strap, with its buckle made from Bronze Gold. The unique formation of the alloy means that this bronze can be worn close to the skin!
"Like some classic Seamaster 300 models, the dial’s hour markers are in the vintage open Arabic style."

A Pioneering History

"The original Seamaster 300 was a popular and reliable choice amongst experienced divers, scientists and militaries working at sea."
