... basically the same the 3237/5237 but, myself, while I do in fact use my chronographs, I have no use for split-seconds, especially since most rattrapantes split only the seconds and not the minutes. Yeah, there is the Lange double-split which indisputably has a beautiful movement but is crazy huge and expensive, really a pocket watch, adding a (to me) useless complication; all this goes triple for the triple-split. Price-wise, the Breguet rattrapante isn't too bad but the price difference between, say, the Patek 3970 and 5004 is legitimately insane. --tim
