Remontoirs require energy to drive them, after a certain point, there wouldn't be enough to run the watch and the remontoir together..

If the watch's total runtime were artificially limited to the limit of the remontoir, then the power reserve would be quite short. Cf the 28 hour range of the dual remontoirs in the new resonance, compared to the total of around 40hrs.
Essentially, the time after the remontoir is time you have to wind your watch at your leisure.

my understanding Patrick once reaching low PR zone, Journe uses power to extend the 'reserve' rather to maintain accuracy (although it is still accurate to Chronometre standards). the moment it is rewound above the threshold PR, the remontoire kicks-in & ...

the timekeeping accuracy is most "unstable" at the extremes of the power reserve. Since the remontoire's purpose is to make sure constant release of power particularly at these extremes, is it not ironic that the remontoire stops functioning when the PR b...

I have to put some reading time into the matter and the difference remontoire types. Specifically the power consumption of different remontoire types. Also, I believe FPJ is the only one that has the remontoire 'disengage'? Eg. the Grönefeld 8s runs throu...
