This rarely used strap, originally from my Reverso Duo, suits the yellow gold VC quite well for summer ...  

I still have my old one somewhere. Lovely Les Historiques chrono you have there. How does it wear compared to the 5110? Both at 37mm... Cheers, John

Without crown, the VC measures 36mm and 5110 measures 37.5mm. But the difference is smaller when crown is included: 39mm vs 39.5mm. So in terms of wearing, I don't feel too much difference in size, in particular where VC is thicker as a chronograph. Both ... 

Brown straps with lighter stitching are my favs.

I imagine it helps dress it down quite a bit and make a formal watch look as good with jeans as with more formal attire.
