My YM40 is running a consistent -1.2sec/day - so if I set it a minute fast at the beginning of the month I know I won't be late!
I know that mechanical accuracy is a bit of a daft concept - if you want accurate, get a quartz etc etc - but I am here because I love what a lump of cogs and springs out together can do!
And my new SD43 is running at 42 seconds off over 45 days...
That’s just worn, all day every day. Only taken off once to reset the date.
Almost the best of the (hundreds) of mechanical watches owned over the last 15years or so.
Gotta be happy with that!

My 1980 1655 Rolex Explorer11 seems to be stuck in a rut since it was serviced about 3 years ago. It gains 2 seconds in every 28 days. I can't make up my mind if this is impressive or ludicrous.
I regulated a £28 Vostok hand winder with a flat head screw driver and no other tools or timographer machine.
I wore it all day and took it off at night as normal.
I made several recording each day against a Gshock atomic watch.
Nobody believes my recordings lol. Every time i quote them literally nobody has a word to say.

Must be time for another time challenge? I think the BB58 won at +_0sec over 6 months without regulation?
That's very good. Following its last service my 16750 was running at about +2 seconds a week, though I haven't checked it for a few years.
I can get my PRS 29A to stay within a few secs of real time for months on end by timing the winding precisely - it gains slightly, but starts to lose after about 38 hours.
As well as modern ones I have a lot of vintage watches and honestly couldn't care less as long as they are within a minute a day.
Who needs to be anywhere within a minute?
Cheers,
Neil.
My SD43 (2017-) started off with that sort of accuracy, running at less than +1 a day. It's now -3.5 a day, which is a bit vexing.
For every tale of perfection, there's this:
An average of -22.9 s/d for the first few days, then we had some lovely timekeeping for a couple of days before it all went up the left. The last reading of -77.9 was the final straw.
Can honestly say I’ve never measured any of my watches for accuracy
If they are obviously way out they would go in for service
