The Speedmaster, initially introduced in 1957, was upgraded with a new case design in 1963. The present reference ST105.012 is fitted with a more robust asymmetric case and 'lyre' horns. The dial would also feature 'Professional' for the first time.
Omega's rich history begins with its founder, Louis Brandt, who established the firm in 1848 in La Chaux de Fonds. In 1903, the company changed its name to Omega, becoming the only watch brand in history to have been named after one its own movements. A full-fledged manufacturer of highly accurate, affordable and reliable watches, its sterling reputation enabled them to be chosen as the first watch company to time the Olympic Games beginning in 1932. Its continued focus on precision and reliability ultimately led their Speedmaster chronograph wristwatch to be chosen by NASA in 1965 — the first watch worn on the moon.
Key models sought-after by collectors include their first, oversized water-resistant chronograph — the reference 2077, early Speedmaster models such as the CK 2915 and 2998, military-issued versions of the Seamaster and oversized chronometer models such as those fitted with their prestigious caliber 30T2Rg.
