Video - How to Determine a Automatic Watch Lift Angle

[SSTEEL 0]

I originally posted this next door, and it deserves to be shared here for anyone who has wondered about a certain watch movement lift angle. I have found some links also which are posted below on various movements lift angles.

 

 

For anyone else interested, here's a great video demonstrating how to easily calculate a watch movements balance lift angle...

 

 

I for one have to admit to being very new to timegraphers, only getting mine this week, and I was always under the impression that the timegrapher lift angle was the physical angle of the watch on the microphone/stand.

 

I only learned earlier today that this is not the case after researching a little more, and of course, ending up here

 

 

Oh and if anyone is interested, here's a comprehensive breakdown of the various balance lift angles by watch brand, and it's caliber..

Lift Angle is in the far right column under, Hebewinkel.

 

Here's an English version, which is more clearer...

Also, following on from the video I posted above, here's more detailed info on the balance lift angle, and related items of interest..

The amplitude of a balance wheel can be calculated from the geometry of the escapement and the relationship of sounds within the tick. Specifically, the interval of time between the unlocking and the drop is used with the beat time and lift angle to calculate a value for the amplitude.

 

More mathematical breakdown...

Nice list! Thanks.

Another useful link which lists Calibres etc..
