Deviation from -2 ~ + 2 seconds/ day rate accuracy
Apr 12, 2023,03:31 AM
Hi all!
It's been a while now, and trust everyone is doing fine.
Just a quick question as i cannot seem to find the answer anywhere else, and i'd thought for sure my friends over here would help, does anyone know, or have your own experience, that since Rolex start setting their in-house rate accuracy tolerance rate to become -2 ~ +2 secs / day across all their calibres since 2015 onwards, besides taking in the usual considerations of the factors relating to how one wears the watch daily, temperature , position etc, overall, how LONG would it take before the calibre starts showing rate accuracies that deviates OUTSIDE of the above stated range? Say instead of so, it now goes beyond -2 ~ +2 and instead keeps on increasing or decreasing further ( -3, -4, +3, +4 etc? )
Assuming say if you do wear the piece regularly, or when you do not, how much of a difference will it make?
Would all this occur before it is meant for it's overhaul? say i take the 5 year mark to overhaul it, will this happen way before that, at say the 3rd year since purchase? Or even at around 5 years it would still be more or less at the original rate accuracy as claimed by Rolex? In other words, what is the length of time that the calibre would need to start showing it's oddities and not staying sharp and true to -2 + 2 ?
Whilst on this issue, now many of you know that i dont really own that much automatics ( for some of you old folks you might remember that i used to NOT even own ONE single piece!) , but does hand winding the automatic timepiece daily, actually help to maintain the good and consistent rate accuracy of said piece? (In this case a Submariner no date) I believe there could be some correlation to this that even if you do wear an automatic daily, that the fact that you could wind it still manually plays some role? Adding further to my belief is the reason why for the Japanese brands say Grand Seiko would when stating that the movement is an automatic, yet would write in brackets, that the movement is "Included with hand winding functionality" 手巻き付き)furthering meaning that one should hand wind the movement as you would a hand wound watch if you fancy? Or does this actually help it be more accurate overall?
I hope to hear from anyone with these 2 points!
Cheers
Stephen
