The Heritage

The Osmior Retrograde Perpetual Date Silver is a 41mm white gold timepiece from the Leroy Osmior Range, representing contemporary architecture combined with Swiss watchmaking mastery. The case houses complex mechanical movement with sculptural design where each angle is engineered to capture and reflect light. Custom strap work by Atelier Casati Milano is required for the non-standard integrated lug design.
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.
