I put on a watch in the morning and usually take it off in the evening.
If (for whatever reason) I happen to be home during the day after putting on a watch - it stays on.
If I go out in the evening, I am likely to wear a different watch from the one I originally put on when I got up in the morning.
On the weekends I tend to wear beaters.
When I was younger (so much younger than today) I used to wear my watch 24 x 7 (shower/sleeping/etc...) now I find I've changed my mind and only wear them during the day.
