Complication inspired by everyday life
Watches with power reserve indicator
A useful addition to any hand-wound or self-winding watch, the power reserve indicator shows how long the watch will continue to function without further winding.
Information is generally displayed by means of a needle that sweeps a segment of a circle from + to - (similar to a petrol gauge on a car), or graduated in hours or even days.
Certain sophisticated watches include a system, inspired by the “dynamometer”, which constantly indicates the amount of tension in the mainspring. As long as the needle remains in a delimited zone, the mainspring is supplying the exact amount of energy for optimal precision. As soon as it leaves this zone, the movement should be wound.
