Each has its unique appeal. 249 is simple but different, provocative, trim, comfortable. 232 is similar, yet elegant, if less unique/different. 372 is bold, strong, and rugged, with each element complementing the other. Fiddy may be the ultimate modern version -- its curvaceous crystal especially. 721 is whimsical with a big, anonymous dial offset by casual blue hands. And the 587/673 are somehow bold and elegant, with the nice MM touch. And for lovers of the lighter dial like Ahoi, the 662/663, of course. I'm sure I've left many out, especially the older ones that are almost unattainable, apart from sergio's pictures ;-)
