Obviously, though, that's all a matter of preference - I like watches on leather, probably more than bracelets which I often find are not quite the right size or get excessively tight or loosen as the temperature changes and think these renders look great on leather.
Sinn do a number of watches with this style lug and they look good on leather - My own Breil Manta looks great to me on a rallye strap.
I think traditional lugs would make this just another chrono... I hope Eddie sticks with his design (experience suggests he has a good feel for what works).
Version A on leather looks spot on to me!
