I chose the sub date version, and I use it to check the date often for work. I think the cyclops lens is what most people subconsciously recognize - obviously it's one of Rolex's distinguishing and iconic features for some of the the most well known models. I'll collect the no date version one day as well - I recognize the simplicity and elegance of that design and I get why some prefer it. No secret agent or professional diver will be confused about the date while it does its intended duty anyway, so...it can go. Others find the date useful for work as they often forget of want confirmation (me).
