I’ve always thought the hands drive the 24hr cycle irrespective of date changing. You’re implying that if I change the date at 2pm (a running watch of course), that at midnight the date won’t change.Long ago a fellow that knew much more about automatics than I ever would told me to change the date between 7 a.m and 12 noon.
This way the date will continue to change at midnight. If I would change the date at, let's say 2 p.m. which of course is after noon that starts a new 24 hour cycle and then the date would change over at noon and not midnight the next day.
My friend never explained what would happen inside the movement if I would change the date outside that window of 7 A.M to 12 noon.
When I pick up an auto in the afternoon and want to set the date from a non running watch, well, that's a different kind of animal.
His friend is partially right, some do and some don't and that's based on the movement.I’ve always thought the hands drive the 24hr cycle irrespective of date changing. You’re implying that if I change the date at 2pm (a running watch of course), that at midnight the date won’t change.
Hmm, I doubt I'll ever find myself changing the date in the afternoon, but maybe I'll try it and see if you friend is right.
Welcome Alex...This is why you should always read the manual b/4 playing with things....This is the very first thing you learn inI just got a Tag Heuer Carrera Calibre 5. It is my first automatic watch and not knowing any better I changed the date at 12.30am. Only later I discovered that I shouldn't do it between 10pm and 2am. How bad was this for the watch?
