nothing but the gen one.
asia 7750 material = bad
swiss 7750 material = excellent
asia 7750 adjustment accuracy = bad
swiss 7750 adjustment accuracy = excellent
asia 7750 accuracy = not better than 8-10 seconds plus per day ,
swiss 7750 accuracy = with a high-end time-level-machine and maybe 2-3 days to check, better than 3 seconds plus per day.
in my auto pams i have always a swiss 7750, and it is a real joy to see the accuracy.
