Replaced battery. Why is it advancing 2 seconds at a time?

I found a way to get my second hand ‘unstuck’. It would only wiggle when I pressed the button to show the charge. After replacing the capacitor and reassembling very carefully, I pulled out the crown halfway and turned it to advance the date by several days at once. The second hand started moving again right away. It was advancing a second at a time not two, so it had charge. When I checked the amount it showed almost full (new capacitor was already charged).

A second hand that pulses but does not advance usually indicates one of two problems: (1) a weak battery that provides insufficient power to the tiny motor that advances the second hand; or (2) a bit of dust or grit somewhere in the watch's gear train that is jamming up the works.
Try testing or replacing the battery. If that doesn't work, some watchmakers can try to blow out (using very gentle air puffs, not cans of compressed air) the watch movement and/or put it on a special machine to try to unjam the gears. It is usually does not make economic sense to perform further repairs on a watch of this price range, though it is also possible to replace the entire movement.

From ParksideJ:

1. click the top button to stop the second hand
2. click the bottom button to reset the timer
3. pull the crown out all the way
4. twist the crown forward hard and fast for a few seconds. The minute hand will start advancing very quickly.
5. when the desired date and time is reached, push the crown back in place. If you missed the time, pull the crown back out and twist backwards. The minute hand will move slowly in reverse. If you twist hard and fast, the minute hand will start spinning in reverse again.

The crown has 3 positions.

Normal screwed down.
First pull out position.
Second pull out position.

Setting the Time:
Pull out the crown to position 3.
Rotate the crown to set the exact time.
Ensure that you are in the daytime12 hour segment by allowing the hands to pass 12 o'clock and notice if the date moved on or not.
If the date changed, then you will need to advance at least 2 hours before moving on to set the date.
If you do not need to change the date, return the crown to position 1.


Setting the Date:
DO NOT DO THIS IF THE WATCH IS BETWEEN 8pm & 2am
Pull crown to position 2.
Rotate the crown clockwise to set to the correct date.
Return the crown to position 1.


Setting the Alarm [12 hour]
Pull the crown to position 2.
Rotate the crown anti clockwise to move the alarm hand to the desired time.
Return the crown to position 1.
To activate the alarm, press the 8 o'clock button. You will hear 2 beeps.
To deactivate the alarm, press the 8 o'clock button. You will hear 1 beep.
NB If the alarm is not cancelled while it sounds the first time, it will repeat again in 2 minutes time. The alarm sound last for 15 seconds. If the alarm time coincides with 1 beep of the countdown, the alarm function will be cancelled.


Battery EOL [End Of Life]
The Swiss ISA 8270 movement uses a 395 cell and will signify a low power state by advancing the small seconds hand 4 steps every 4 seconds.


Setting the Countdown
You can specify a countdown of between 1 and 10 minutes.
Press the 4 o'clock button to enter setting mode. You will hear 1 beep.
Press the 4 o'clock button to move the central timing hand successively to the desired countdown time.

Countdown tone:
There are 2 beeps every minute.
in the last minute:
50 seconds=1 beep.
40 seconds=1 beep.
30 seconds=2 beeps.
20 seconds=2 beeps.
10 seconds and less=1 beep every second with zero being 1 second long beep. Timer function automatically starts.

Press the 4 o'clock button to view the seconds elapsed on the hour/seconds counter sub-dial.
Press the 4 o'clock button to reset.


Resetting the Hands:
If the hands do not zero correctly, which might occur after a battery change or a violent shock, you can make adjustments by doing the following settings as long as the countdown is not in operation.
To correct the hour/seconds counter sub-dial, pull the crown out to position 2 and wait 1 second.
Press either the 2 or 4 o'clock button; the central timing hand will turn and stop [not necessarily at 12].
Press the 2 o'clock button to increment the hours/seconds counter sub-dial hand to position it at 60.
To correct the central timing hand, press the 4 o'clock button to increment the hand to the 12 position.
Return the crown to position 1.



If the battery had been replaced, the central timing hand defaults to the 10 minute position. If the battery had not been replaced, the central timing hand will return to the previously set position.

This is an early warning sign to get the battery changed .The watch should still keep time for a couple of weeks.

You need to replace battery.
Q/A from swiss army website.
Q. How do I know when the battery needs changing?
A. In select models, the battery end-of-life indicator signals that the battery should be replaced within two or three days. When the battery is low, the second hand stands still for 2-4 seconds, and then speeds up to the correct time. This indication will last for approximately one week, and then the timepiece hands stand still.

For Casio Waveceptor:

check you battery!

Unscrew the crown and press the lower button, this should advance the minute counting hand one press ata time. Pull ot the crown a further stop to advance the seconds hand and again to advance the tenths counter.
