Lift angle for cal 51011?

I've just found on the web a nice chart for IWC's lift angles but I'm missing cal 51011.

I searched in the archive but I haven't found it.

Could you be so kind to tell it to me please?

Thank you in advance.

P.S. Guess what's the IWC calibre this chart reports to have the minor lift angle?

Lift angle for cal 51011?

All IWC calibres 51xxx did have a lift angle of 42 degree

Thank you. not bad at all. (nt)

Is there a "best" lift angle?

or can it be compared by the frequency of the watch, where it apparently is not possible to say that 21.600 is better or worse than 18.000 or 28.800. So, does the value have any discriminating function?

Very little knowledge of mine.

Hi Paul,

to my little, very little knowledge, lift angle effects the isochronism, the higher will be the lift angle, the more it'll cause problems to isochronism.

Obviously, a bigger amplitude of the balance wheel may help decreasing drawbacks caused by a high lift angle.

Regarding frequency, I always keep in mind the example of the whirligig, the more it turns faster, the more steady it is but applied to watches this becomes just one of many factors to consider.

I hope I expressed some decent sentences nonetheless my poor english.

Regards,

not in my opinion, but Google can help you

To look up the answer, I suggest some basic research such as Googling "lift angle" . The best discussion I found after 2 minutes of research is linked below.

Thank you, I first searched the archive...

I forgot to mention that I did this before I posed my question. I already saw some interesting technical explanation, but could not find out to which value to strive, if at all useful. flyrobfly36 gave some indication though. Quite probably there will be a kind of trade-off here too, like with the frequency, where fast is more stable and slow is more wear-and-tear friendly.

Link to chart?

Do you have a link to the chart for IWC's lift angles?

Thanks very much

You have an e-mail, I preferred to do so since>

the chart contains also data not related to IWC.
