Description
The Citizen 6651A is the last ladies' selfwindig movement from Citizen. It is still
made until today by Miyota under the code 6T51 and is used in the current ladies' automatics.
Unlike the mens' movement caliber 8215, the balance on the 6651A / 6T51 beats with
28800 beats per hours and thus the movement achieves good precision.
As all modern Citizen automatics, the ball beared rotor winds the movement only in
one direction, clockwise. This has been proven as the most efficient winding way.
The caliber 6651A can be wound manually. In the second crown position, the time and
weekday (bilingual) can be adjusted and in the outmost position, the date can be
advanced by one.
