I usually change out bands once or twice a week, mostly to color coordinate the band color with the watch face I use with it to change things up every so ofter. I have five sport loops, two sport bands, a black link bracelet and a gold Milanese loop that I have certain uses for each one. Mostly the sport loops and sometimes sport bands are for everyday/workout use. The link bracelet and Milanese loop are used more for dress up occasions or when I just want the watch to look a little fancier for casual everyday clothes.
