Battery change Gw-A1000A G-shock?

[The Doc]

My dependable and bomb proof Gw-A1000A has stopped working and parked its hands all top dead centre. Date wheel also moved itself to 1.No buttons do anything.

Its a solar G-shock from 2012 and it lives in a room with natural light, not in the dark. It gets light usually.

Obviously I've tried charging it in direct sunlight, but nowt.

What's the chance that it just needs a new Ctl920 battery?

Have you tried a hand reset and sync?
Although the manual does say these symptoms mean it need charging
Have you stuck it outside for a day?

If it's 10 years old I'd say it's probably due a replacement.

I'm going to go for one last chance at charging, out on the garden bench for 12 hrs, then I'll try some of the suggestions above.
Panasonic battery looks like £18 supplied, so we'll see

OK, massive success and thread update.

I left this in the sun yesterday, outside.
I did the lawn, cut back the tomatoes and got a little drunk.

So I forgot about the watch.

And this morning.... it works !!

Tried to receive the synchronisation signal, but it didn't work.
Remembered that you need to set the Home City, so I did, (also read the manual fully, as I should have done from the start)

And why the picture above ?

Well I live 29 miles from the MSF signal broadcast at Anthorn courtesy of Babcock Ltd on behalf of the MoD. https://www.npl.co.uk/msf-signal

AND I'm direct line of sight of the transmitter mast. Marked with a red circle in the photo taken from the top of the garden.

.....

So it got hold of the signal pretty easily and we are 100% function again.

god I'm a geek.


here's the tech info on the signal, for those interested:

Is it Ant-horn or An-thorn?

[The Doc]

"Anthorn's name means 'the single thorn bush'. Before the dissolution of the monasteries in 1536, salt was panned in the area by Holme Cultram abbey."

pronounced /ˈænθɔːrn/ AN-thorn


"Originally no more than a cluster of cottages and small farms on the shore, the village increased in size and importance in 1942, when an existing First World War landing strip was developed as HMS Nuthatch, a Royal Naval Air Station.[1] The RAF station closed in 1958, and Anthorn Radio Station is now the site of a large mast field for the NATO VLF transmitter, the NPL time signal and an eLoran timing signal.[2] The Admiralty housing development, larger than the original village itself and about 0.62 miles (1 km) to the east, remains. In 1870–72 the township had a population of 197."

I think that puts that to bed

its AN--THORN

I’ve got 8 solar atomic c g shocks, 3 of them are over 10 years old and still show high charge with no issues. Note these take a long time to fully charge - the window of a high charge is quite large. If I were you I’d give it a couple more days of full sun (seeing as it had gone into recovery mode) to get it properly juiced up - that should keep it on high until next summer at least! Lastly I’d move it’s resting place somewhere a bit brighter!

Apologies for the belated "thank you." Most illuminating.

[The Doc]

Well you'll love this....
I'm off tomorrow and it got me thinking, it's a 20 minute drive to the station, could I visit?

I wrote to the NPL. Can I visit please?
They said no, but gave me this video which is also interesting

The Anthorn time is referenced to the Teddington NPL time. And a nanosecond is 30 cm long! And accurate time is needed for high frequency trading (as well as GPS, and lots of other things , which I knew about)
