MINUTE REPEATER. PERPETUAL CALENDAR.

The music of cathedral gongs

This self-winding Grand Complication with minute-repeater and perpetual calendar combines technical excellence and elegance in a white gold version with a blue Grand Feu enamel dial. The case features a subtle interplay of curves accentuated by polished and satin-brushed finishes. The minute-repeater chiming on two "cathedral" gongs stands out for its deep, rich sound.
