-1.8 seconds since 25th march... Quite good for a 36 year old non thermo-compensated watch...
I have a bit of a fondness for Seiko's 7548's and have always been very impressed by the accuracy of these old watches which I normally find is a few seconds a month.
My current one (the 3rd I have owned) came from Bodo on this forum via SC:

I last set it when the clocks changed to BST in march and had not thought to check it untill today and it has lost 1.8 seconds so running at 4-5 seconds per year.
In the mean time it has been worn in the boiling mid summer heat of the Pyrenees and the icy chill of wild camping on Helvellyn, canoeing, cycling and general 'beater' duties.
Has anyone had similar accuracy from older basic quartz movments?

Yes, its highly accurate - but my impression is that its above average for quartz, but not an order of magnitude better, even for basic quartz. Most people never even bother checking the accuracy of their quartz watches between the times the clocks change. I had a cheap Pulsar which I abandoned - when I rediscovered it a few years later (not sure how many - probably 3, but I can't be sure), it had only gained a minute in that time.
I have an old Casio, AMW-320R, cased in China, Japan movement it says in the back. Looks a bit like A Seiko Arnie.
I bought it around 2-3 months ago from this very forum.
I set it, accidentally, 1 second fast when I received it, checked it this morning...
Still 1 second fast.
I'm just a very naughty boy.

I may have forgot one or two, apppologies.
I suppose I never really timed my watches untill I gained more interest a few years back. The quartz I have had since have generally been circa 3 sec p/m (new tag F1/omegas seamaster quartz) 10 s/p/m (older 80s F1) or 20+s/p/m cheap eBay rubbish.
The older 7548's I have had beat them hands down.
Absolutely from my 7548, I thought it was because it's an over engineered movement and very high quality. Like it so much I bought another which reminds me, must refresh the sales post!
recently bought a 1983 6530 popped a renata in it and after a week its spot on the the atomic clock...it cost me nothing. a lovely slim piece of 80's style.
