Silicone balance spring can snap !

 

Silicone, unlike metals, is much less forgiving to very slight imperfections. For example, if a nano-scale crack is formed during production, it can propagate with time and ultimately result in the breakage of the spring. Preventing this failure mechanism requires extraordinary quality control, which may not be feasible 100% of the time even with the best clean-room technologies of today. That is why I would shy away from any watch possessing a silicone spring balance in spite of their superiority with regard to magnetism. Cheers Jim
