Specific highlights
• Ultra-thin movement: 4 mm thick (4.5 mm including the carriage).
• The flying tourbillon gives the piece an undeniable elegance, with the carriage suspended from a
single axis just above the dial at 12 o’clock.
• The ultra-thin carriage (2.8 mm) weighs only 0.2 g thanks to its three titanium bridges.
• The visual effect produced by the flying tourbillon is accentuated by the presence of the Piaget “P”
initial. The asymmetrical nature of this decorative feature required meticulous development to ensure
the overall balance.
• Tonneau-shaped movement.
• Astronomical moon-phase, only 1-day discrepancy every 122 years.
