Monopoussoir Chronographe

Chronographe de Précision à Roue à Colonnes & Poussoir Coaxial

“Tactile chronograph command concentrated into a single coaxial crown.”

The Monopoussoir pays homage to 1930s doctor's chronographs and observatory timing instruments. Operating start, stop, and reset through a single sapphire-inset pusher, the lateral clutch lever slides with silky tactile resistance over a hand-black-polished six-pillar column wheel.
