Casio Waveseptors analogue / digital going out of sync

I own three Waveseptor type watches..

1. Is analogue display plus digital and is recharged by light.
2. Is analogue display plus digital and is NOT charged by light, needs
battery replacement occaisionally.
3. Is digital only display, recharges by light.

All three are kept in perfect sync by radio, for the digital section.
All three remain in perfect sync with the correct time, on the digital
sections/digital displays.

If I wear either 1 or 2 the analogue display will gradually loose by a
few seconds per day and need to be reset using the hands reset buttons,
to match the digital displayed time.

If I don't wear 1 or 2, but simply leave them on a window sill, the
analogue keeps in absolutely perfect time with the digital.

Has anyone come across this issue before please?

3 always maintains perfect time in it's digital display. I have good
reception of MSF Anthorn, the UK time transmission.

Inadequate signal strength or receive sensitivity in the receiver
design, with movement of the watch and orientations to the transmitter.

No cure for that, other than taking it off every night to resync,
pointing it towards a known transmitter...

Other point is that UK MSF goes offline sometimes, or generates a low
power unreliable signal. Perhaps ask them ?...

You misunderstood....

The digital time works absolutely perfectly, always syncs with MSF - it
they all receive a good strong signal from MSF, always spot on to a
fraction of a second with actual time.

The digital side generates the once per second pulses to advance the
mechanical hands. On my wrist, both watches 1 and 2 will gradually over
the day loose several seconds, but only the mechanical analogue time
display - the digital time display remains absolutely accurate.

If instead of wearing 1 or 2 I leave them unworn, the mechanical
analogue display will remain in perfect sync with the digital time for
days, weeks, months.

So the question is - why would wearing them upset the mechanical
analague time keeping? I have had watch 1 for around 15 years and it
has only exibited this problem for the past couple of years.

Sorry abut that, but if you have had the watch for many years, it's
possible that the internal lubricant has dried out, or is contaminated
with dust particles and the watch needs a full stripdown, clean and lube
by now. All mechanical devices need maintenance eventually and will
fail if that's not done, just a matter of time. The fact that your
watch is primarily electronic makes no difference if there is mechanical
drive to analog hands.

I standardised on a brand and model of watch decades and have several of
the same model and they have all suffered from that problem along
the way. Also restore old cameras and they are renown for shutter and
timing problems with age...

If that is the cause, why do they keep perfect time off the wrist, then
suddenly begin having problems once on the wrist?

Another possibility might be that after 15 years, the hardware has
developed intermittent faults, such as dry solder joints on the
internal pcb. The vibration and movement on the wrist could cause
such faults to show up. Really don't know, but a full service
from a specialist might provide some answers. If it were mine and
I really liked the watch, I might have a new movement fitted, if
still available...

I have your No 1. Mine occasionally displays the same symptoms.

I have concluded that it is something to do with getting it too close
to a magnetic field - an electric motor or working with magnets.
Whatever the cause it makes the stepper motor that drives the second
hand miss steps.

On mine it only seems to be the seconds hand. The minute hand stepper
does not seem to skip steps - it may just be that It has never been
close to the source of the problem at the time the minute hand steps, or
possibly the minute motor is more robust as it drives the hour hand as
well via motion work.

I've been more concerned with the obvious seconds discrepancy and tend
to regularly correct the analogue seconds hand, so really i have never
noticed if the minutes hand suffers the issue or not. I will try to pay
that more attention in the future.

I should tighten 1 & 2 up.
