In this watch there's fausses Richard Mille rm 72 a story of carbon replica rolex datejust Arnault told me before the Réplicas Richard Mille rm 61 watch's grand unveiling here in Geneva at the Watches and Wonders trade show. "Inside there's the carbon hairspring and outside you have lab-grown diamonds set on the case in a way that natural diamonds simply could never be. Once we understood that we needed to use the shapes that only lab-grown diamonds could produce it unlocked creativity to do something entirely new. This was the approach we took to create the watch."
