I've observed previous people on this forum to get so obsessed with their mechanical watch's performance that they cease to enjoy possessing it. Most of us, if we buy a car, check its advertised top speed, after a careful look around and perhaps only once, and very discreetly and without drawing attention to ourselves, thrash a ton of tin up to 115 mph and relax, sweaty but satisfied, never necessarily needing to do it again.
If we knew that most standard speedometers are about +8% and that we are not reaching the advertised speed, we would keep taking the car back to the dealer. A mechanical watch is a little like the new car, be satisfied with it if it works within reasonable specification or buy a quartz, saving a lot of money into the bargain. Or (ssch) read the time off your cell-phone.
I have an enjoyment of owning, within my means, a variety of mechanical movements. Some have their own quirks, some are more accurate than others but, I like 'em all! ...UB
