On one hand, you can marvel at how little they drift during a single power reserve. Could be seconds, which is barely noticeable in everyday life.
On the other hand, some others (Seiko 5...) can drift minutes in a single reserve... And so what? In a day and age when we measure everything with maniac precision even during a random person's day, it's beautiful to lose some control and gain back some leeway with regards to time.
I love that it is "about 22:00" rather than 22:03:37.
