Caliber 2460WT is of course self-winding, and the rotor is made of 22k rose gold. The entire thing is made in-house by Vacheron Constantin (naturally), and the 36.6 caliber offers 40 hours of power reserve, beating at 4 Hz, with 255 components. The whole watch, inside and out, is just beautifully finished, and in fact the watch is Geneva hallmark certified.
