Hmm, I’m pretty sure, from most videos on bilibili featuring that watch, they are indeed selling the black version, which will be $2k+. The rotor’s build quality isn’t really on par with real artisan de geneve. There are also carbon fiber versions with uncoated skeleton movements, which is said to be much cheaper.They sell few versions but the black one is genuine. They only have one version of this movement as far as i know, which is shown on the gold one.
Dial hands caseback bezel etc on the black is gen. Dealers love to throw in genuine pictures and say it's their new release...
It's tight enough I'm not worried it will moveWith the hollowed out balance bridge, what will you use to secure the position of the hairspring stud?
