There will be a memory-keeping capacitor in there somewhere that is

replacing it will fix it.

I'll bear that in mind, if I have to go inside.


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
