My seiko monster's accuracy is between +20s per day when the watch is fully wound (when i wear it all day long, plus 5-6 minutes of swirling it!) and -5s with normal use (8-10 hours).
Is something wrong with the isochronism? I would like it to be more consistent...

A competent watch maker can certainly fix it, though it might cost more than you're comfortable spending on an inexpensive watch

Understood, i'll leave it as it is! (until it gets worse...)
Thanks!
