Speedy Pro 105.012 - question for Speedy experts
Guys, does this look right? It has the later chrono hand, but according to an article, the last period's 4th version had the later chrono hand type.
Also, what's the difference between this model and 145.012?
Thank you all in advance!

Rei, i was going to comment on this 1963 'pro' model yesterday, but the kids were here and i was forcd to drive an Xbox :) my comment would have read that it is possible or even quite likely that this dial is a slightly later than original addition. the r...
