Every now and then resets to some sort of default, 01 01 2005 data and
Tokyo radio system , so never resets to local time codes.
Have to then reset it manually.
No problem suggesting a low battery or any other timekeeping problem.
I've tried holding down various buttons to check if its due to bad
switch contacts but never induces this default.

There will be a memory-keeping capacitor in there somewhere that is going either faulty (age) or intermittent (cold solder). Either way, replacing it will fix it.

I'll bear that in mind, if I have to go inside.
At the moment I'll go with the business about button-D

I'll snap back a sewing-pin , after pushing it into the D button to
wedge it out, and swathe in a dot of hotmelt glue.
Resetting the thing , before doing so , of course

Soldering iron against a sewing needle , bending while melting into the
button to force outwards, then a dot of hotmelt over, old-endsnippered
the excess.
Stayed proper time for 2 hours now, whether it stays un-reset for the
next week, the longest otherwise, we'll see.

It reset during the cold of the night, I'll wedge open the otther 3
buttons, JIC, then get inside 'when' it resets again.

So how old is the battery you haven't gone inside to replace?

There's a reset in there by shorting 2 test points - you usually have to do
that after replacing the battery.

Can't hurt to try that, and its a good excuse to put a new battery in
anyway.

Lithium coin cell shelf life is somewhere in the direction of 10yrs, but
mine uses the oddball CR1620, so who knows how long its been hanging on the
display rack.

I'll probably go in there later this week.
At the moment I'm checking it runs normal non-radio control for a few
days. Set it to London time yesterday, and did not engage RC!, at some
point it decided to move its time zone to New York time so 5 hours
behind. Pressing button C, brought it back to UK time, currently still
the "normal" slightly wavering correct UK time having passed thr a very
cold night

Looks like I won't go inside this week. It decided of its own accord to
engage radio control and has run fine since, including very cold nights.
I decided to grind back all 4 plastic knobs, so a fingernail is required
to operate, and as hollow buttons , some hotmelt in there to stop dirst
entry. Why this watch and most of the cameras I've owned plus a
"Dremmel" without a shroud around the mains switch (serious safety issue
there). A crazy business having to recess switches and shroud switches
on handled and transportable mainstream products.
I'll give it anothe rweek , on probation
