Abstract (en)
[origin: US2005174893A1] In order to make a wheel-shaped balance ( 1 ) lighter, while maintaining sufficient mechanical resistance and good dimensional stability as regards temperature variations, the felloe ( 3 ) and the arms ( 2 ) of the balance are made of titanium or a titanium-based alloy. This enables a sprung balance oscillator to be made with a larger diameter than normal for the same frequency, or having a higher frequency with the same dimensions as a usual oscillator.
