GenTLe 1,510 Posted October 17, 2014 Gen Valjoux 7750 has hand sizes (in mm cent): 120 min 200 hour 25 center sec 20 subdials (small sec / chrono register hands) Gen Valjoux 7750 has hand sizes (in mm cent): 120 min 200 hour 20/22 center sec (the one I measured this evening is around 22 cent mm) 17/20/22 subdials (small sec / chrono register hands, again measured this evening on 2 different ones that showed different sizes) Does anyone tried to swap the center second/chrono register wheels of an asian 7750 with an ETA one in order to make the movement to fit the gen hands?

Cheers, GenTLe Be careful how you measure. Swiss ETA 7750 Hour 2.00mm Minute 1.20mm Center Seconds 0.25mm Subdials 0.17mm Asian 7750 21.6BPH Hour 2.00mm Minute 1.20mm Center Seconds 0.25mm Subdials 0.17mm Asian 7750 28.8BPH Hour 2.00mm Minute 1.20mm Center Seconds 0.20mm Subdial 0.20mm I can't remember, but I don't think the center chrono seconds is compatible. I think it was the depth of the jewel, but I don't have one to try right now. Share this post Link to post Share on other sites
