The Audemars Piguet selfwinding movement imparts a special cadence to the Millenary Pianoforte watch:

• the direct-drive central seconds avoids friction
  
• the cross-through balance bridge ensures enhanced reliability
  
• an over 60-hour power reserve guarantees running accuracy
  
• a balance-stop device keeps the seconds hand motionless during the time-setting process
  
• the adjustment remains stable thanks to a variable-inertia balance equipped with eight inertia-blocks, an arrangement that is also conducive to accuracy
  
• the calendar makes an instant jump
  
• the date can be adjusted rapidly
  
• the bidirectional automatic winding is ensured by a 22-carat gold rotor mounted on a ceramic ball-bearing mechanism
