A virtually completely handmade timepiece with 95% of components (approximately 272 parts including wheels, pinions, plates, pivots, screws, dials, hands, balance, and even the balance spring) made entirely by hand using only hand-operated tools with no computer assistance. Each watch takes approximately 6,000 hours (around three years of person-hours) to make by a single watchmaker from start to finish. Features a one-minute tourbillon in a 43.5mm white gold case. Limited to 2-3 pieces per year. Winner of the prize for best Men's Complication Watch at the 2020 Grand Prix d'Horlogerie de Genève. The finishing includes a distinctive 'gratté' (scratched) finish on the rear of the movement.
