Having seen the work in progress photos before, amazed to see the perpetual cal finally complete!
Then I scrolled down further at a movement shot, immediately saw something at 9 "wait, whats this...regulator looking thing needed for a perpetual cal?". Had a stare for five seconds, "why- wait theres hammers? Insanity"
Looking forward to see your repeater tourbillon chiming!
