I don't consciously rotate watches; instead, I wear whatever strikes me that day. Yes, it is work to set dates and days, but oddly I find that to be part of the enjoyment of watches. Anyway, today is a Speedmaster day, and I get to show off my latest strap that arrived yesterday from Vietnam. It is Stingray, dyed black, and polished so each "dimple" is highlighted. It seems to go well with the fine details on the bezel and watch face (my wife is not crazy about it ):
