Quartz Minute Repeater, ca. 1992
The Battery R395 is under that Shield
And the case back contains a lot of instructions how to start the watch after a Battery replacement. Many Citizens have a similar initial setting procedure:
Pull the crown out to position 2 (hands setting position) and press all three push buttons down for ca. 2 seconds, after the confirmation chime, push the crown back in.
The watch will then chime a "ding-dong" to confirm the initial setting. Most of the alarm chronographs will indicate the successful initial setting with a beep. Analog and digital watches will also issue a beep and normally all LDC elements will show after the initial setting. The description of the further setting is only for his Minute Repeater Cal. 6760:
Pull the crown out to position 2 again. Press button A (at 2 o'clock when facing the watch from the front) to adjust the center second hand to the 0 or 60 position. Press button B (4 o'clock) to set the small 24 hour subdial to 0:00 AM. Press button C (8 o'clock) to move the weekday indicator to SUN. It is very important to finish this step exactly as described here, because the further settings depend on these settings here.
Push the crown back in
Pull the crown out to position 2 again - yes, I know it is the 3rd time - to set the hour and minute hands to the correct time. Use button B(4 o'clock) to adjust the time on the 24 hour subdial to the time you have just set with the crown.
Push the crown back in
Now you are done with the most important settings. For all the following settings, you will not need to pull out the crown to position 2. Further settings are:
Date: pull the crown out to position 1 (the watch has to be in Time Mode, that means the weekday indicator is on SUN) and press button A (2 o'clock) to set the date.
Alarms: select the alarm mode with the weekday hand, pull the crown to position 1, press button B (4 o'clock) to adjust the alarm time on the small 24 hour subdial
Seconds: this is really nifty feature! Push button C (8 o'clock) until the weekday hand stands on SEC0. Now pressing button A (2 o'clock) will have the following nice effect: the center seconds (which are actually part of what Citizen calls sub watch in the manual) jump to 0 or 60, thus you can synchronize the watch with a time signal. The feature I really like is, that the main watch will now "wait" (the small second hand in the subdial at 3 o'clock stops) until the main watch and the sub watch are in synch. Very easy synchronization of the main and the sub watch.
