About Leroy perpetual calendar:
The retrograde perpetual calendar in the Osmior line is an exclusive creation from the company’s watchmakers who drew their inspiration from the exceptional timepieces in teh brand’s private museum.
For almost a cenutry and a half, L. Leory has specialized in the production of watches known as “Grandes Complications” and was one of the word’s first manufacturers to offer models fitted with a central retrograde perpetual calendar.
The movement (calibre) of this masterpiece is produced in the Val de Travers, Switzerland in collaboration with a boutique independent company with a worldwide reputation for producing top-of-the-range components. It is then heavily customized, modified, regulated and fitted in Besancon, France, by the master watchmakers of Les Ateliers Leroy.
