I was surprised though to learn the 876 movement is "only" 262 parts. Just looking at the watch and knowing it's a perpetual I would have guessed a much more complicated calibre. I wonder what a Duometre would look like after a similar skeletonization treatment, I bet it would be epic!
I was with the understanding that the more complicated models went back to JLC also. The boutique manager explained to me they don't have an option, they must send models to Richemont and from there the service center will determine which watches do go back to La Maison and which are serviced here i
