Why not 45 degree?

Response to Why not 45 degree?


At 45° you would either have to make the watch much thicker or to reduce the diameter of the balance wheel.

Greubel Forsey did not wish to do the former for reasons of esthetics nor the latter for reasons of chronometry - generally the larger the balance the better the timekeeping all else being equal.

JLC's Gyrotourbillon is a true masterpiece of watchmaking engineering; however, GF put chronometric performance higher up the list of priorities.
