Every dive watch has a 60 minute watch bezel on them for dive times that can also be used to adjust the time when the watch gains or loses time. Most automatic watches gain time though when you wear them. Instead of adjusting the time every week or so. Set the watch 5 or 10 minutes slow, and as the movement gains time adjust the dive bezel, and then reset the watch when you want to after it gains 5 or 10 minutes. This will give you 10 or 30 minutes of use before having to reset your watch after a month or so. I say 15 minutes is the cut off time because the hour hand is hard to tell what side of the hour it is.
