Bouée · Calibre 1
A hand-wound movement combining a one-minute flying tourbillon with a four-year mechanical calendar programme.
Overview
Some mechanisms are understood immediately. This one takes a little longer.
The tourbillon remains in view. The calendar works beneath the surface. Between them, the movement reveals only what is necessary and leaves the rest to be discovered over time. Only eight pieces will ever be produced.
Front architecture
Display layout
The dial separates timekeeping from the calendar displays to improve legibility. Hours and minutes remain central, while the day, date, and month are assigned to dedicated indications, leaving the flying tourbillon fully visible at the lower edge.
Complications
Flying Tourbillon
The balance and escapement are mounted within a cage that completes one rotation every 60 seconds. The cage is supported from below, providing an unobstructed view of the regulating assembly.
Perpetual calendar
The calendar mechanism distinguishes months of 28, 29, 30 and 31 days. It coordinates the date, day, month and leap-year displays through a 48-month programme.
Continuous operation avoids routine correction for short months and leap years until the Gregorian exception in 2100.
Movement architecture
The reverse side reveals the winding system, wheel train, and supporting plate structure.
Broad finished surfaces are balanced with open mechanical areas, keeping the movement’s layout and power path easy to read. Plate contours, polished edges, and blued screws define the construction without hiding its function.
Surface Treatment and Structure
Broad, parallel waves run across the visible plate. Directional light makes the repeating cut pattern clear without hiding the shape of the component.
