Superior, Classic Watchmaking in Leroy’s Osmior Collection

The House of Leroy (Montres L. Leroy) has a lovely collection that is proud to be able to offer in our exclusive selection of luxury timepieces.

This exceptional collection, titled ‘Osmior’, includes incredibly intricate, yet traditional complications. It characterizes the superior watchmaking skill and prowess demonstrated by Leroy over more than two centuries of crafting timepieces.

Leroy’s Osmior collection includes the house’s complicated timepieces, such as the Retrograde Perpetual Calendar, Automatic Deck Chronometer, and Chronograph. The name, Osmior, is also imbued with the brand’s longstanding history in watchmaking, and is identified as a special alloy that is proprietary to the House of Leroy. This special alloy is crafted primarily with gold, yet exhibits a color similar to platinum.

The incomparable design in the Osmior collection is extended from the lovely, aristocratic hallmark – the date is denoted with a sweeping, blue central retrograde – to the lustrous gold dial and hand-guilloched watch face. An internal highlight of the Osmior watches is the 48-hour power reserve, due to the double-barrel design and the bridges, which are finished in Cotes de Geneve.

Leroy is truly an authority in the world of horology and luxury watchmaking. Its history lends itself to the best design and most informed craftsmanship. offers three combinations of the Leroy Marine Automatic Deck Chronometer timepiece in 18K rose gold. The watche is available with a silver, black, or silver and gray dial. Our selection of Leroy Osmior timepieces also includes the Chronograph watch, a Monopusher Chronograph, and 18K Rose Gold Moonphase. All of the luxury watches feature the incredible Leroy craftsmanship in a hand-guilloche dial and most have 18K rose gold hands.
