He earned an honorary diploma from the watchmaking school in La Chaux-de-Fonds and is celebrated for his highly precise chronometers. His watches received numerous awards at various chronometry competitions held at the Observatory. Notably, he entered several watches in the Paris Grand Prix, including our example, which features the inscription “Grand Prix Paris 1900” on the movement.
