I was so impressed when I saw it last year. It's certainly an extremely difficult watch to make, the rarity and the intrinsic value is going to be very very high. The instantaneous perpetual calendar is nice (and oh so difficult to make, as you need so many sub regulators to provide the energy to spin the discs in an instantaneous fashion).
The separated balance wheels is very impressive, but the part that's even more impressive is the switching mechanism and how the watch doesn't theoretically loose even a second between switching. Of course, when the next balance wheel starts, it needs a few minutes to get its "natural beat" so the first 20 minutes or so after switching I wouldn't expect the watch to run perfectly accurately.
The other part that I find interesting is what lead to the necessity of this creation? Is it an accuracy pursuit? Is it a "stretch the power reserve" pursuit? Is it a convenience pursuit so people don't have to reset their perpetual calendars? Could they make the "slow beat" balance wheel larger? Could they make a mode where both balance wheels run and a differential averages out the accuracy (would resonance help or hurt here)?
It is definitely a VERY COOL WATCH that will be very rare compared to other perpetual calendars.
I could have a video interview about all the nuances of this watch that would fill a 20 minute episode!
Back in SIHH 2018 I was super impressed with the VC Traditionelle Tourbillon Automatic 6000T too. My review of that watch is below.
