Catalogue Essay
Developed in conjunction with COMEX and the legendary Jacques Cousteau, the Ploprof was the first waterproof watch designed and built solely for diving professionals. It took Omega approximately 4 years of extensive testing before launching the watch to the public in 1970. The prototypes were tested to 600m at the Omega factory and subsequently tested to 1000m in the Golf du Lion off the coast of Marseilles (France) as confirmed by the Extract from the Omega Archives.
The French-speaking development team nicknamed the watch “PloProf” in reference to PLOngeur PROFessionnel: Professional Diver in French. The present watch is fitted with the sought after mesh bracelet, reference 1266/237 complete with the diver extension. It is presented in a stunning condition with its original, beautifully patinated dial and hands that have slightly faded to a light orange color.
Massive and unique in its design, this Ploprof prototype is a rare opportunity that will surely appeal to collectors of exceptional tool watches.

Swiss | 1848Omega'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.
