You said the watch gained 1 minute in 10 days. That's a fast watch, not a slow watch. Pulling the crown for 6 seconds every morning should do you.
Alternately, you may know this already but you can speed up or slow down a watch overnight by resting it in one of several positions:
Lay the watch face up to make it run faster overnight
Lay the watch with its crown pointing up to make it run more slowly overnight.
These are directions from the Rolex care booklet.
So every night if you rest your watch with the crown up, you will compensate for its nature to be fast when you wear it.
