Osmior Chronomètre Observatoire Pièce Unique for Only Watch

As one of the 43 manufacturers that have generously donated unique timepieces for the 6th edition of Only Watch 2015, Leroy has created the "Chronometre Observatoire – Piece unique Only Watch" with a dial, case, and movement made of aluminum. It’s inspired by a historical timepiece in the brand's museum: an aluminum travel clock with grande sonnerie dating from 1894.

The hand-wound Leroy Manufacture caliber L200 features an innovative, direct impulse escapement with 98 hours of power reserve – reflecting the independent brand’s focus on precision. This unique watch will be sold in Geneva on 7 November 2015 during the Only Watch charity auction, with all funds raised benefiting medical research for Duchenne Muscular Dystrophy.
