Nice find! Would love to see on jubilee. As to service, I’m torn, given you can hear some rubbing.
Edit to add- I just bought an EXP II White 16570 that I could hear the “whir” of the rotor. I took it to my watchmaker who adjusted that part, added a new screw, and sent me on my way for $50. I’ll enjoy it for awhile then maybe take it in for service in a few months. Runs like a top.
