If others on here are like myself,then that watch running +/- whatever over the week wouldn't actually matter or be worn for a week if changed as most do,that being a daily change of watch.
Perhaps it could be if worn for the week,but even then are most of us ruled by a couple of minutes plus or minus on our watches.
Can't really say you'd miss a bus or train, & most people get to important meetings/Interviews well before the agreed times.
100% Just the WIS on watch forums to talk about.....Hence the replies & reasons given to justify after reading this!.
