In horology, a remontoire is a secondary winding mechanism that is periodically rewound from the main source of energy, such as a mainspring. Its most common function is to regulate the force that drives the clock's timekeeping mechanism, although remontoire mechanisms can also be used as a mechanical amplifier to drive the hands of large tower clocks. Horology is the study of the science and art of timekeeping devices. ...
A remontoire, from the French word 'remonter' (to wind), is a constant force device used in a timepiece whereby the main source of power periodically winds a spring or lifts a weight to drive the timepiece's escapement.
The second class of remontoire, the spring driven type, was invented by John Harrison during development of his H2 marine timekeeper in 1739.
A movement equipped with a remontoire is fascinating to watch, as there is a periodic movement of the rewind mechanism usually mediated by a fly fan (air brake) that spins around.
