3712
Hi Gentlemen,
I used to own a 3712 with 3 red dots in the power reserve. Recently, I know that some 3712 has 4 red dots in the power reserve indicator.
May I ask any of you know the reason why?
Is it only because they are from different period?
Thank you very much
3-dot 3712
I've heard the 3-dot markings on the pwr reserve indicated an early production 3712, and the 4-dot's were later productions that year. I don't know at what point the changeover occurred. Hope this helps
