Regards Mark Hi Mark, Do you mean the lift angle or the beat error? Lift angles for some of the movements are as follows: 6xxx - 54.5 deg 7xxx - 53 deg Beat error can and should be adjusted to 0.0 ms. |

You might get some deviation in your lift angle in multiple positions (i.e. crown down, dial up, dial down etc). The trick is to adjust it so it is, on average, as close to zero as possible in as many positions as possible.
e.g. if I get 0.0 dial down, 0.1 dial up, 0.2 crown down, I'm happy.
The Swiss literature says it should never be more than 0.3ms.
