Hi Me again At this time. I would like to ask your opinion about new hair spring ?? and. Have you ever seen this type hair spring ??? Ok. Let me try to explain There is picture. That show you normal hair spring Almost movement use This kind hair spring. I...  

Hi, I am far from an expert or a watchmaker, but I tried to follow your thoughts, but did not understand... Two parameters that will set the frequenze of your movement are the length of the hair spring and weight of the balance wheel. (Of course there are... 

While one is expanding the other is contracting. But I think it would be very difficult to set the timing of the two springs identical in this configuration as they have very different geometries and I don't see how they could be treated separately. But m... 

Why do we really need simmetrical vibration at balance wheel? Because classic swiss lever is designed for this. But what about new escapement with separated locking-impulse (etc.) stages (like Daniels)? If we do not except simmetrical, but only periodical... 

But why is the Swiss lever desiged this way?.... 2 reasons: 1) To allow the balance wheel to turn as much as possible without disturbance. This is to improve the timing qualities. If we don't use as much of the possible free arc as possible in both direct... 

I'll stick with quartz! =8^{D>
