DJC explained on 30/11/2018 :
THe batteries don't last long because of the dumb way it keeps time.
ItÂ* checks the signal once every 24 hours, probably around 01:15. It
then windsÂ* itself forward to 00:00, pauses, then forward again to
the correct time. AllÂ* this winding round every night runs the
battery down, they sometimes lastÂ* less than a year.

I have never seen one do that, rather they pause if ahead of time, or
pulse the hands forward until correct if behind true time.
I have a similar clock but it has type C battery. Lasts ages. Only time
it winds round to twelve is when you change or pull the battery.

The same with mine. On a battery change each of the hands will quickly
tick around to 00:00:00 and wait there for 30 to 60 minutes until it
receives the transmission and then immediately moves the hands to the
correct time. The one I have in my kitchen I look at on a regular basis,
including in the early hours of the morning, and I've never seen it
reset to 00:00:00 in the same way.
