As my collection grows, I find that often during the day I change the watch I am wearing. Perhaps in the morning I put on my field watch for the morning choirs, a diver or GMT for the office, and a sports watch for the evening when back at home. Or any other combination, depending on the circumstances.
What are your wearing habits (say, on average)?
I am on a weekly rotation. Takes a lot of will power and discipline.
I'll switch for certain tasks if needed. Otherwise I'll often wear a watch for a few weeks until I get bored of it.
I switch every day, small 3 watch collection so far so its no problem.
