Abstract

An apparatus for advancing a date indicator of an electromechanical calendar watch. An hour indicator is driven through two normal operating revolutions of twelve hours each while keeping the date indicator fixed. The hour indicator then is driven through at least one more revolution at a speed much greater than the two normal operating revolutions to advance quickly the date indicator one day through a gearing connecting the hour indicator to the date indicator.
