The Osmior Range LL102/1, seen from the bench
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.
