Omega 2850 Seamaster 18k Olympic 1956

Omega Seamaster XVI Ref. 2850 SC – Olympic Heritage in 18k Gold (1956)

This exceptional Omega Seamaster XVI from 1956 was created to celebrate the 25th anniversary of Omega as official timekeeper of the Olympic Games, marking the Melbourne Olympics of that year.

This particular example is the rare 18k yellow gold commercial version, offered for sale following the Games — combining historical significance with timeless dress watch elegance.

The beautifully preserved golden dial features a subtle, evenly developed patina, adding depth and character while maintaining its original charm. Paired with classic hands and a clean layout, it perfectly reflects Omega’s mid-century design language.

Inside beats the reliable Omega Cal. 470 automatic movement, making this watch not only a piece of history, but also a highly wearable vintage companion.

A refined and meaningful Omega — where heritage, craftsmanship, and design come together.
