A French perpetual calendar and also a pencil! Lundi, Mardi, Mercredi etc. The gaps are filled with stars. The letters and numbers are of a lighter blue enamel, and the frames that surround them are of a darker blue. A subtle touch. The pencil works by the press of the button - gravity helps it drop down (and then in again when you press the button and tip it upside down). French stamps for silver to the bale
