Your Nicolas Rieussec looks great!
Now on Villerets being large - they also have smaller ones such as the Vintage Pulsograph at 39mm. My chronograph grand feu enamel is 41mm, quite big by my standards but somehow, the design of the curved back and the leather covering the lugs gap makes it look less big on my small wrist. I guess this is why some PuristS (eg Hororgasm) can even carry the large 47mm Montblanc Villerets!
