A timepiece having a toothed calendar ring and a driving wheel for advancing the calendar ring, wherein the driving wheel comprises a hub and a completely closed toothed rim having a driving tooth. The rim is connected to the hub by a resilient member so that the driving tooth makes way for a tooth of the calendar ring when the calendar ring is driven by means other than the driving wheel.
