Stunning!!! Congratulations to both you and Capt G. He makes some awesome blanks and you really did a fine job of turning them beautifully.
I'm always a little partial to the Minnie and Micky blanks...but the big ones are just amazing. Doc
Yes...all the watch parts are real. CaptG sells both certified (real) and non-certified (who knows) rolex faces. You do have to pay a premium for the certified real.
I was intimidated too at first, but if you're comfortable turning and finishing acrylic, then you should be OK with these. You should also know how to do a CA finish, since that's the way to recover should you accidentally expose the edge of a watch part.
