Interestingly, Vacheron Constantin chose to retain a mechanical movement for the small profile watch. Inside is a manually wound 1005 movement, that is just 3.6mm thick. Don't expect too much life out of it though as you need to wind it at least every 30 hours - certainly enough for a good night (and morning) out. With a total of 36.5 karats of the attractive new flame cut diamonds, the Lady Kalla serves its purpose well to highlight a novel, but classic looking piece of watch jewelry for women.
