  • Catalogue Essay

    This diver's watch is a very rare left-handed version from the 1970s. The watch features a bi-directional bezel that can be adjusted and locked by a red push button in the band on the right. The crown is furthermore protected with a locking nut, and the 'square' is actually a crown.

    Reference 166.0077 was made in conjunction with COMEX and Jacques Cousteau, the legendary French naval officer, explorer and conservationist. The watch was used for dive explorations, most notably for oil research. Divers lovingly dubbed the watch 'PloProf', a shortened name for Plongeur Professionnel. The development and testing for this watch underwent four years before the 'PloProf' was launched in 1970. At the time of its launch, the model was among Omega's more expensive watches. Research suggests that the watch retailed for CHF 720 on Milanese bracelet, making this model quite rare today.

    Omega

    Swiss • 1848

    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.
