Remontoire is a complex and specific term that refers to a device used in mechanical watches to regulate their timekeeping. However, some synonyms exist that can be used to describe similar concepts. For instance, "escapement" is a term that is frequently used in watchmaking to refer to the mechanism that regulates the movement of the watch's balance wheel. Another synonym for remontoire is "constant-force mechanism," which describes devices that are used to ensure that the energy released by a spring is consistent and uniform over time. Finally, the term "regulator" is also sometimes used to describe a device that regulates the timekeeping of a mechanical watch or clock.
