What would be the hand hole diameter for a 6CAMC movement?
I tried to measure the hands myself. I get about 1.0 / .63 for the hour and minute. The second looked bigger when next to a replacement hand that should be a 0.20 mm hole.
I checked the Ranfft Watches database, and they don't have this movement, but all the other Bulova 6 movements with center seconds, 6CAC, 6BKC, etc.. are 1.10 / 0.60 / 0.18.
But I also found this picture of an old hand assortment, and a 6BKC is listed as 1.09 / 0.65 / 0.28.
