Earlier quoted context omitted.
> 10 minutes of daily drift is perfectly tolerable Heh I feel bad when I'm 10 min late to a call, but if I had your watch I'd be 20 min late!
I'd wind the watch and adjust it in the morning, and will be 2-5 minutes late in the evening. But at times I would adjust it during the day while watching time close to another, more reliable time source (like a public clock in a train station, for instance, or TV news in a shop window). After all it only takes a second to adjust: pull the crown, turn it a tiny bit, and push it back in :)
If I need the precise time, I can pull out my phone or just ask another human who nearly because they will surely have a phone :)
(Note to non-watch enthusiasts: we are talking about the tolerances on very old watches; a modern $100 mechanical is usually accurate to within 5-10 seconds a day)
