You can see this base caliber through the watch’s sapphire caseback, and it is important to note that the perpetual mechanism of this watch is 100% Vacheron Constantin. The rotor of the 1120QP is hand-skeletonized and really looks the part from the rear. The newness of this particular watch is really about the grey dial, which is actually an opaline slate grey. The dial itself is convex, with circular pearl-shaped minute markers and pink gold applied hour markers – the hands are also in 18k pink gold, keeping things nice and warm.
