The Heritage

The Leroy Osmior Range Tourbillon Automatic Regulator Black is a contemporary watchmaking masterpiece featuring a 41mm white gold case with integrated bracelet. This model represents a fusion of Swiss horological tradition and bold, distinctive design, embodying Leroy's manufacturing philosophy that combines haute horlogerie with luxury architecture.

Made to Measure

The strap for this watch is made to measure

On the Leroy Osmior Range the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.
