Zenith: How Zenith’s fusee and chain work together

- Zenith developed a special complicated watch, the Academy Georges Favre-Jacot, to celebrate its 150th Anniversary in 2014.
Zenith traces the roots of this watch, which is equipped with a fuse-and-chain constant force system, to its development of marine clocks. In this video the head movement designer of Zenith explains the function of a fuse-and-chain, and he also answers to the questions: How do you protect the chain when you’re winding the watch?
And how do you keep the watch running when you’re winding the watch?
Thank you. I am a young amateur horologist, that is to say: a 71 year old forest dweller who is fascinated by these little engines and enjoys working on them. I have recently acquired a couple of antique fusee watches, with the intent to restore. I enjoyed your video.
Very informative. It would be nice to see the watch in action and some 3D animation of course :)
Very nice. John Harrison would be very pleased to see his maintaining power system still in use.
the fusée chaîne was developed by the French Ferdinand Berthoud, isn't it?
@@sideleyOriginal I always thought it got traced back to Leonardo da Vinci?
Thank you very much. I wish there were some animations too...
Near the end of winding does the spring that keeps the watch going during winding get reset? Or does it get reset as the watch runs under the main spring?
Awesome thank you 👍
I would rather see standard style dials on expensive watches so that a glance is all you need, but perhaps one is not meant to use them on a daily basis even if you can afford them.
Exactly.
Wow that's pretty confusing when you speak english and french and you try to listen to them speaking french but it begins to speak in english...
1:36 is this Solidworks?
Fusion 360
yes this is actually solidworks not fusion 360
@@cookiedufour As a long time solidworks user I can confirm this is not solidworks!
So it's unlimited energy or what ? 😂
Energy from the mainspring pulling the fusee via the chain and giving a near linear power output to the train. Thereby improving regularity of beat over time. In old Verge escapement pocket watches this system was essential. Accuracy of timekeeping is improved.
No, it's using stored energy in the spring. The stored energy is from the person winding the clock.
