The power reserve’s autonomy of reservoir’s watches can reach up to 36 hours.
The power reserve refers to the operating time of a mechanical movement without needing to be winded up. The power reserve is represented by a sub-dial, that we essentially find on top of the range automatic watches. Which hand indicates the tension level and the duration of the remaining time in hours. The power reserve’s indicator is present on every watch of the RESERVOIR collection with a design that is inspired from gauges and tachometer in particular.
