The 5726 is in theory and on Pictures a very nice watch. I've been interested in it several years ago and tried the White and black 5726 on my wrist. Result: I've got a serious Issue with the fact, that the Date windows are so tiny, that They're basically Not nicely legible. And the dial Looks too crowded. My conclusion was Not to buy a 5726.
5711 is therefore my choice between These two.
