Power Reserve

A watch’s power reserve indicates its total running time when fully wound. All of Rolex’s watches with Superlative Chronometer certification, as well as Tudor’s watches with manufacture movements, offer an estimated 70 hours of power reserve. This is significantly higher than the average amount of power reserve in regular mechanical watches, which may range between 36 to 42 hours.
