While the 215PS may not at first sight be much to look at, it is in my personal experience one of the finest handwind movements, not from the perspective of decoration, but for durability and precision of timekeeping.
I’ve not had the same luck with Lange’s or VCs for example (for regulation, not durability). I once had a Richard Lange, that came out of the box at 12s/day but never got to Patek, Rolex or Omega regulation standards or positional error reduction even after multiple attempts by the factory. And this was touted as a chronometeric high precision watch that even has a stop mechanism when the power reserve runs low. I could never get past this as I felt a promise had been violated and I parted with the watch.
And my VC cornes de vache chronograph likewise was poorly regulated out of the box and just wouldn’t get there even after 2 “attempts” by the factory. It makes little sense to have a highly quality regulating organ if your watchmakers are cutting corners getting your wares out the door.
Sorry for the tangential rant, but I’m increasingly of the belief that precision and accuracy are table stakes for high end watchmaking. If you skimp on this, the rest of the claims seem hollow. And this is where Patek, Rolex and Omega shine.
So coming back to the small 215 movement, it is anything but small, when it comes to performance
