I've only tried on the 5230G, just before they discontinued it as well as the 5230R: the fit on the wrist of the 38.5mm case (with 46.7mm lug-to-lug) was perfect. But I think I much prefer the "pebble smooth Calatrava case" of the 5110 and 5130. The 37mm of the 5110 case (with 46.3mm lug-to-lug) would probably be a perfect fit for my rather slim wrist and I love the swirling guilloché pattern and lozenge-shaped hands. But your 5130 looks very nice too: the city disk breathes a little more and there's the nice O-shaped “Observatory” hour hand and the beautiful sunray guilloché pattern. But im afraid the 39.5mm case (with 49mm lug-to-lug) might be a little large for my wrist. I would really need to see these watches for real! And as I love rose gold, it's the 5110R and the 5130R which I would like to try on.
