Accuracy - How do you know? How much do you care?

As long as it’s within a couple of minutes over 24hours that’s fine with me (trustworthy enough for a cursory glance during the day). Computer/car/phone are never far away if a time check is pivotal. It’s all about the object as far as I’m concerned.

I've only really become interested in the accuracy of my watches since I acquired my Speedmaster FOIS a couple of years ago. It was my second "good" mechanical watch and I was interested in comparing their performance (my other watch is a Seamaster Pro 2551.80). I check the timekeeping of my watches using an atomic clock app on my mobile phone every couple of days. I'd adjust them so that they're always within a minute of reference time. Don't like being late to an appointment!

It's funny but I would be happy if my FOIS was running at +6 seconds a day but I'd be unhappy if my Seamaster was doing the same thing. I guess it's because the Seamaster is chronometer rated and +6 secs per day is only just within specs, whilst +6 secs per day is well within specs for the FOIS. It all comes down to what your expectations are.

And iPhone also doesn't need service, unless you damage it!

No but they also won’t last 60+ years

My thanks to all who have posted, I now feel more more normal. Though it could be none of us are normal, hmmmm, now have something else to OCD about!

I use the Dinky/Watchville clock as well. If one of my senior citizens deviate too much over a week of wearing, off to the spa. I really have no objective standard for “deviate too much” .

I use a timegrapher. You can get one for about 100-150 USD. It can tell you some other things about the health of you watches too.

I'm sure we all have a collection of watches not just a few. You are bound to set the time for the watch you wear that day if you rotate here and there. I always have to set my 861 seamaster. Manual winds suck but I still like to do it. So no, I don't really care for accuracy. I pick up my watch, set the time and wear for no more than a few days. Rinse and repeat.
