The problem with this scenario is that you are assuming an efficiency of over 100%.
Nov 28, 2023,03:16 AM
When the two barrels wind down, some energy is lost moving the gears and the hands. Yet more energy is lost moving a rotor to feed these two barrels. That rotor would have to be over 100% efficient to generate the same amount of energy back into the two barrels, plus the surplus needed to show the time. There is energy lost in every friction point. The balance wheel even loses energy from the resistance of the air inside the case! You would need to operate the watch in a vacuum, have 0 friction, or have a magical winding system that puts out more energy than it receives.
Think of regenerative braking on an electric car. What you are positing is to have the battery charged to full capacity solely from the regeneration, but in a lossy system, this is impossible because you need to first move the car using some external energy before you are able to regenerate via the friction created by the brakes while slowing the car.

A Mechanical Watch Movement that Never Stops
By: SALMANPK : November 27th, 2023-22:19
and I don't mean not just an Automatic movement which requires the wrist movement to get the rotor to rewind it. A watch movement where even if the watch is stationary and not on a watch winder or a wrist keeps on ticking and not stopping. I am not an eng...

You would always need an external source of energy…
By: Carlos22 : November 27th, 2023-23:05
Due to the friction inherent in a mechanical movement. The energy stored in the mainspring is used up when moving the gears and the hands. In order to re-wind the mainspring you need an external force to compress the spring. This constant of energy in a c...
I agree
By: SALMANPK : November 27th, 2023-23:10
it does need a source of energy to push the rotor to help rewind the mainsprings in a three barrel movement where the third barrel is used to store energy to help push the rotor so that the movement never runs out of power reserve and since it is a time o...
No Sir

Wanted that watch badly. Too bad nothing ever came of it. Where did the prototype go?
If the watch is stationary and in vacuum - impossible.

Sorry for being lazy but will just quote Wikipedia Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source...
This isn't physically possible
By: donatello2468 : November 28th, 2023-00:26
What you're describing is a perpetual motion machine () at the scale of a wristwatch, which isn't possible due to physics/thermodynamic laws. The closest we have in this case is as Nico pointed out, the JLC Atmos which although seems like it's running per...

...you would solve all of the energy problems in the world. But you might raise the ire of global energy consortiums and of course they would have to eliminate you. You're gonna need a good exit strategy.
Hahaha
By: SALMANPK : November 28th, 2023-01:56
well the movement will be wound up initially so not out of thin air to store energy in three barrels of which two unwind to help run the time only movement and the third barrel is just there to push the automatic rotor so that it can rotate under its own ...
Yep exactly that's why it's impossible
By: donatello2468 : November 28th, 2023-05:19
You're expecting a rotor rotated by one barrel's energy to further produce enough energy to recharge three barrels, which is basically making energy out of thin air

Impossible.
By: andrea~ : November 28th, 2023-09:39
Such movement would violate the laws of thermodynamics, since what you are talking about is a perpetual motion machine. If we could make a watch that functions in that way then we would also be able to produce infinite energy. The conservation of energy w...
I am not proposing a perpetual motion machine.....
By: SALMANPK : November 28th, 2023-10:26
there are movements with 2 to 4 barrels which are used for multiple complications which exist today. My proposal is that instead of having multiple complications we can create an automatic movement with 3 barrels of which 2 are used to power the watch mov...
You would still need to provide energy to the third barrel
By: andrea~ : November 28th, 2023-18:29
If you do that you are just subtracting energy from the rest of the movement, since you are creating more friction by increasing the number of interacting parts. All of the energy employed with the intent of making the power reserve be longer would actual...
thanks!
By: andrea~ : November 29th, 2023-17:33
there is a watch like this, if I understand you correctly
By: jaspermccrea : November 28th, 2023-12:46
where the mainspring charges a smaller spring that drives the escapement. The small spring is kept at the same tension, only charging from the mainspring when needed, so the watch theoretically keeps better time. One of the smaller high end manufacturers ...

So i did. photos didn't come so good so i will try to edit it. Thanks you
Not a 100% mechanical solution . . .
By: Jim14 : May 19th, 2024-14:51
but if the goal is for the watch to always keep time without winding, how about the Ressence Type 2? A brilliant and elegant solution!
