Been seeing how accurate my watches are on the wrist. So far I have:
Orient, -1 second after 6 hours, so about -4 seconds a day.
Seiko Green Military, +4 seconds after 6 hours, +16 seconds a day.
Seiko 5 Black PVD, 0 after 6 hours, dead on.
Seiko Kinetic, 0 after 6 hours, dead on.
Seiko 5 Blue, +2 seconds after 6 hours, +8 seconds a day.
As I accumulate more, I will add what the accuracy is. I am using a digital stopwatch over 6 hours to see how far each watch is drifting under normal wearing.
All of the mechanicals are well withing their rated specifications, which are +30/-15 a day.
