Particularly surprising to me is how generally unloved 5496 is despite platinum Calatrava style case, innovative dial with raised date markers and for me me, overall beauty. I would think the retrograde function would be very popular, but it seems the opposite is true.
Despite my small wrist I find 5496 very comfortable to wear. Probably because of the style of the case and relative thinness.
Will be interested to know how you feel about 5159 and 5496 when at some point you get to see them in person and try them on.
