This Omega Chronomètre à Tourbillon is one of twelve examples originally produced for observatory precision trials. The manual-wind movement, caliber 30.I.1947 with 25 jewels, was manufactured in 1947 and features a tourbillon cage designed to reduce positional error.

In 1987, the movement underwent an overhaul, receiving rhodium-plating, anglage, polishing, and Cotes de Genève decoration. The movement was finished and assembled by Franck Muller. The watch is housed in an 18k yellow gold case featuring a transparent case back and a push-button mechanism for time-setting, protected by an olivette. The case was manufactured by Jean-Pierre Hagmann, and the dial was produced by Tille.

This specific example carries the movement number 10595941 and is equipped with an anonymous 18k yellow gold deployant clasp.

Design

Case and Dial
The movement is set within an 18k yellow gold case that features a transparent case back to allow viewing of the tourbillon movement. The case includes a side-mounted push-button for setting the time, which is protected by an olivette. The case was manufactured by the casemaker Jean-Pierre Hagmann. The dial features a guilloché pattern in the center and is marked with Roman numerals. The auction description notes that the hands are later replacements. Tille is credited with the production of the dial.

Provenance and History
These chronometers were designed by Jean-Pierre Matthey-Claudet based on plans by Marcel Vuilleumier, the director of the Ecole d’Horlogerie of the Vallée de Joux, and regulated by Alfred Jaccard. The watches competed in observatory trials in Kew Teddington, Neuchatel, and Geneva between 1947 and 1952. The watch underwent its modern housing and assembly in 1987. Archival information from the Omega Museum indicates the movement was previously owned and finished by Franck Muller before being cased for this series.
Movement and Tourbillon
Originally designed for observatory precision contests, the movement incorporates a tourbillon cage, which functions by rotating the escapement parts and balance to minimize positional errors. In 1987, seven movements from the original series were modified. This process included rhodium-plating, anglage, polishing, and the application of Cotes de Genève decoration to the 2/3 plate. Documentation indicates that Franck Muller performed the finishing and assembly of this movement during the 1980s.
