Pointer-type jumping date display, Master Grand Tourbillon
An ingenious patented jumping date mechanism has been developed so as not to hide the Tourbillon carriage from view.
The 15th and 16th date of each month are positioned on either side of the Tourbillon carriage opening. The date can be adjusted in either direction.
