Hi all y'all, as my friends down south say --above is a quick video shot at GTE 2012 in Geneva of the Tensus watch in action. You can see the double escape wheel --the lower and upper are only out of synch by one beat of the balance, as the constant force spring is re-armed every time the balance is impulsed.

Easily one of the two or three most interesting pieces of watchmaking in the last few years, especially if you are a chronometry buff and interested in watchmaking solutions to chronometric problems which use traditional watchmaking methods, not exotic materials.

Very interesting

Hi Jack,
very interesting, it would be great to learn more about this constant force system, which seems much more simpler than other similar devices....
