Clockwise Balance Cock
Cal. 291 is a full calendar movement from Universal Genève. The dial layout is distinctive, with subdial pointers at 3:00 and 9:00 that resemble a chronograph (though they show date and small seconds, respectively) and apertures at 6:00 and 12:00 to show month and day, respectively. Some versions show moon phase and month by pointer at 6:00.Images are taken from official publications and are used here for commentary and educational purposes.
