I started accumulating watches about 15 months ago; by the middle of the year I discovered I had more than I was comfortable with, that I have to keep to single figures. I got rid of a couple and stopped buying just anything that caught my eye.
Instead I learnt how to let desires slowly focus themselves, how to let them test themselves against time and competition from other things I might want. I got my last watch in mid-September and now have another on the way, and I have been consistently happy with my collection for about six months, usually wearing each watch for a few days at a time
