I switch straps almost every time I wear them, except for my SKX009 as I installed a Strapcode Super Jubilee and adore it so much that I almost never take it off of it. I really don't usually like the stock straps/bracelets that come on the watches that I buy (inexpensive ones) aren't really very good.
I don't think I would ever buy a watch that I wouldn't open up and work on myself. So I think I won't ever spend more than around $500, so the stock "wrap" has hollow end links, or is really uncomfortable and usually has a bad clasp too.
I have a small collection of watches and a large collection of straps.
