I have.

Since the chronograph motor 1400 operates the display unit 1230 for 1 second, the display unit 1220 for 60 seconds, and the train wheel of the hour chronograph 1211 and the minute chronograph 1212, the chronograph motor 1400 operates.
By arranging 400 at a position corresponding to approximately 9 o'clock to 12 o'clock on dial 1002, the order of transmission of the driving force of the motor can be as follows.

That is, the display units 1230 to 60 for one second

The contact is made by contacting the negative pattern of the circuit board 1704 with the negative side.

Therefore, the path from which the negative power is supplied from the power supply 1500 to the IC 1702 is as follows: the power supply 1500 → the negative terminal 1504 → the negative pattern of the circuit board 1704 →
It becomes IC1702.
