OSMIOR AUTOMATIC RETROGRADE PERPETUAL CALENDAR PINK GOLD
Presenting the Osmior Retrograde Perpetual Calendar, a technical gem with a dial as intricate as its features. At a glance, the day, month, and moon phases are obvious, the dial engineered with both machine-work and manual touches. The name “OSMIOR” derives from an archaic alloy comprising mostly gold with a tone of opulent platinum. Bygone days saw it shape cases for Leroy Grande Complication watches, and it stands for the same values now—grace, finesse, subtlety, and brilliance—echoed in the L.Leroy timepiece creations.
