That's what the differences between 1st and 3rd book, but I wonder if there's information about those speedies that I've mention such as digital speedy, automatic speedmasters, Japan automatic speedy, speedmaster moonphase (valjoux), speedmaster perpetual calendar, speedmaster mark 2,3,4,4.5,5 then the diver speedy, and pre Omega chronograph etc? I had the AJTT book but the info there isn't that deep including the variation existed. As I want to collect the more affordable speedy beside my moonwatch because those rare speedy prices are getting out of hand, I want to have affordable alternative without breaking my bank.
