About Omega:
Founded in 1848 by Louis Brandt in Switzerland, Omega has grown into one of the most respected and innovative names in watchmaking. The brand’s early focus on precision earned it accolades at international observatories and competitions, setting the stage for decades of horological achievement. Omega became the official timekeeper for the Olympic Games in 1932, and in 1969, the Speedmaster Professional—nicknamed the "Moonwatch"—made history as the first watch worn on the lunar surface during NASA’s Apollo 11 mission. Omega’s innovations continued with the introduction of the Co-Axial escapement in the late 1990s, a groundbreaking movement that dramatically reduced friction and improved long-term accuracy.
Omega’s lineup showcases a wide range of iconic models that reflect the brand’s legacy and versatility. The Seamaster, introduced in 1948, is a favorite among divers and famously worn by James Bond since 1995’s GoldenEye, blending technical capability with cinematic cool. The Speedmaster remains one of the most storied chronographs in existence, while the Constellation is known for its refined design and chronometric precision. The De Ville collection offers a more elegant, dress-focused aesthetic, often featuring high-end complications and meticulous finishing. Omega continues to lead with innovations like Master Chronometer certification, METAS testing, and antimagnetic technology—ensuring that its watches are not just beautiful, but built for the demands of modern life.
