dbutlerman Posted May 20, 2010 Report Share Posted May 20, 2010 Howdy - Got a question for the movement people out there. I've been working on my 3717 and have a question. From what I understand the hands from my 3717 (A7750 movement) won't fit ETA/Valjoux Swiss 7750. Then I stumbled across this website that sells A7750 movements (http://www.wltnp.com/Asian%20movement.htm) and according to their specs, the A7750 movement would accepts ETA hands. Can somebody offer a definitive answer to what are the hand sizes for an A7750 and what are the hands sizes for a Swiss 7750? Thanks! DB2 Link to comment Share on other sites More sharing options...

dbutlerman Posted May 20, 2010 Author Report Share Posted May 20, 2010 Does it matter if it is the High Beat 28,800 A7750? Link to comment Share on other sites More sharing options...
ubiquitous Posted May 21, 2010 Report Share Posted May 21, 2010 Oops... Sorry, got my wires crossed. High beats have the hand sizes outlined above. Slow beats should have the same size as Swiss 7750s... Link to comment Share on other sites More sharing options...
Ronin Posted May 21, 2010 Report Share Posted May 21, 2010 Correct. A7750 21.6 = Compatible hands sizes. A7750 28.8 differs. Link to comment Share on other sites More sharing options...
