Automatics only.Casio G-shock. One, two, three weeks and then I stopped counting...still spot on--and I don't even count it as part of my "collection". The point is? Or perhaps better defined parameters? (Automatics ONLY, hand wound, spring drive, quartz....)
What device are you using to measure that has the resolution to display a 0.14 sec deviation?Sky-Dweller 326933, +0.14 sec/day, worn 7 days/week and stored crown up (YES! Crown UP!) at night. :-d
Of course, timing deviation is subject to change for various reasons over an entire year. :think:
"Worst case" timing deviation so far has been dial up at night, with -0.89 sec/day. Still, THAT would only be a <theoretical> loss of 5-1/2 minutes per year. Not too shabby! :-!
Modern Rolex don't seem to follow the 'old rules' for customer timing deviation adjustments they used to supply years back with the watch paperwork.
Must be due to advances in movements it would seem?
