n mechanical horology, a remontoire, (from the French remonter, meaning 'to wind') is a small secondary source of power, a weight or spring, which runs the timekeeping mechanism and is itself periodically rewound by the timepiece's main power source, such as a mainspring. In precision clocks and watches it is often used to 640-553 exam place the source of power closer to the escapement thereby increasing the accuracy by evening out variations in drive force caused by unevenness of the friction in the geartrain. In spring-driven precision clocks a gravity remontoire is often used to replace the uneven force delivered by the mainspring 70-643 exam running down by the more constant force of gravity acting on a weight. In turret clocks it serves to separate the large forces needed to drive the hands from the modest forces needed to drive the escapement 70-270 exam which keeps the pendulum swinging. A remontoir should not be confused with a maintaining power spring, which is used only to keep the timepiece going while it is being wound.
