if you have the older low beat A7750, then you can purchase a swiss 7750 as replacement. The hands will fit.
If you have the newer high beat A7750, then you need new hands to swap movement.
I just bought my first rep here. A Tag Heuer Carrera Racing. I am going to wear it as a beater Mon-Fri at work. Otherwise, I will wear my Gen Omega PO. I plan to buy one more rep and one more gen. Don't know which ones yet, that's why I am here.
Also, when I wear my rep, I am free advertising for Tag Heuer. I look good in it, and conversations occasionally leads to my watch. Tag should pay me instead imho.
It's that simple. No politics, no bitching, no bull$hit. That's all I have to say.
