Catalogue Essay
Any Ploprof captivates attention as few other watches: the enormous angular case design, the large red button for the bezel lock, the prominent bezel… It is safe to say it is a watch unlike any other, furthermore endowed with advanced technical waterproof capabilities and a distinguished history (it was notably used by COMEX as well as Ocean Systems Inc.).
The present example is however set well apart from the “standard” Ploprof. In fact, its movement number starts with “000”. Such numeration was reserved by Omega for prototypical or R&D pieces. And indeed the Extract from the Archives confirms that it was realized internally by Omega R&D department for testing purposes. The watch in fact mounts a different caliber than the usual cal. 1002 found in production Ploprof. It features a Chronometer movement cal. 1001, especially developed to resist water temperature variations. While it makes sense that a chronometer movement was employed on such test pieces (a highly accurate movement would yield more accurate results about temperature-related variations), the byproduct of this choice is that this is one of the extremely few Ploprof timepieces to be fitted with a Chronometer-grade calibre - furthermore fully confirmed and explained by the Archive. A truly incredible discovery which will delight the connoisseur of fine and unusual timepieces.
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.
