I picked up the Seamaster 300 because of its luxurious and vintage-like appearance.
According to the release, the alloy, named Bronze Gold, is a patent-pending new material developed by OMEGA that revives the bronze that flourished in ancient Greece using modern technology. Composed of 9K, palladium, silver, and other materials with a seal of purity, the alloy prevents green tints while also allowing the wearer to enjoy the wonders of aging.

Bronze gold with an exciting change in expression.
Sapphire crystal glass caseback.
The Omega logo is at the head of the buckle.
The "no-no" was the good old-fashioned sandwich dial. The indexes and numerals are placed on top of each other on cut-out plates, and the Super-LumiNova applied to the dial is made to float. The open-style Arabic numerals used in the 1960s are also irresistible.
The Seamaster 300 was OMEGA's first professional diver's watch, launched in 1957 along with the Speedmaster and Railmaster.
With its black dial, luminous indexes, large hour hand, and the most advanced high-pressure waterproofing system and diving bezel of the time, the Seamaster 300 was everything a diver's watch should be: an unmistakable timepiece.
Clad in bronze gold, the Seamaster 300 looks as if it has been pulled up from the depths of the ocean after 68 years.
