i have something(idea) to share with people who like the watch.
actually i have a idea, but i am not sure that is good or bad.
there is nobody who i can ask......
at first i am sorry that my bad English.
the idea is the way to control the torque.
there is watch that has long power reserve. 7days, 10days, or 30day.....
long power reserve watch has big and strong main spring(barrel).
sometimes strong barrel make the problem. ---- knocking and no stable(isochronizm).......
so i think the system to control the torque. i mean....
if the torque is too high(fully winded), make it decrease(the torque).
when the torque is getting low, make it increase(the torque).
i am not good at English. so let me explain by drawing......
for example, there is 100days power reserve watch. you can see the drawing, and there is power reserve indicator.
(drawing is just for explain, something is wrong.! pinion size....)
there is friction spring(B), this spring touch the wheel pinion(C).
there is special part(A). this is a eccentric lever. the movement is same with power reserve hands.
this drawing explain fully winded situation.
this drawing explain NO winded situation.
when fully winded, torque is high---------make friction high(spring"B" touch pinion)----------make torque low
then 10days later, 20days later, 50days later,-----torque is getting low-------friction getting low-------torque is not big change!!!!
i am not sure that you understand what i say..... i am sorry that my English...
i really want to ask......
Have you ever seen same system or similar ?????????????????
what do you think about this system.. good or bad...????????????
thank you very much for read ..
