My two exceptions are iwc pilot chrono in 42mm as it fits with the pilot feel to wear bigger. The other is my 43.5mm montblanc minerva collection villeret chronograph, here my heart won out with the enamel dial, huge movement and balance wheel, finishing, and snail dial.. I just wanted it. I do feel it fits OK on my wrist because it is not too thick (12mm IIRC?), but I would wear it more if it were smaller. I do think lug to lug distance makes as much or more important of a contribution here.
