About Leroy Automatic Tourbillon Regulator
The automatic tourbillon regulator model in the Osmior line is an exclusive creation from the company?s watchmakers who drew their inspiration from the exceptional timepieces in the brand?s private museum.
Specifically developed by Leroy, this model contains an ultra modern version of the tourbillon system with an escapement (wheel and lever) machined from pure diamond. This reduces the weight of the mechanism and increases its hardness. As a result, the high performance and chronometric stability of the watch can be guaranteed longer than is possible with a classic system.
This movement (calibre) is produced exclusively for Leroy by its Manufacture de la Valle de Joux, in the heart of the Jura mountains of Switzerland. Each part of the movement is then assembled, regulated and finished in Besanon, France, by the master watchmakers of Les Ateliers Leroy.
Each Leroy Osmior automatic tourbillon regulator undergoes a series of final checks at the National Observatory in Besanon. The watch is then individually certified as a chronometer, according to the ISO standards in operation.
