Citizen Chronomaster CTQ57-0961 Date Change Over from 2/28 to 3/1

Last night I shot this two minute and fifty seconds HD video showing the perpetual calendar complication of the A660 Citizen Chronomaster in all its glory:



The date change starts to take place at around 12:00:17 AM.

The A660 movement in the Citizen Chronomaster uses a high speed motor (10,000 revolutions per minute) that drives the calendar wheel and it is fully independent from the motors that drive the hour/minute and seconds hands.
