Abstract

Watch comprising a mechanism (50) for driving a device (1) that displays a time-dependent value, this drive mechanism (50) itself being driven by the movement of the watch, this watch also having at least one first correction element (42) acting on the display device (50) via a clockwork mechanism (2) of the drive mechanism (50), and at least one second correction element (48) acting directly on the device (1) that displays the time-dependent value, the watch being characterised in that the drive mechanism (50) is arranged so as to drive the device (1) that displays a time-dependent value in both directions when the first correction element (42) is operated, and so as to be overridden when the second correction element (48) is operated, acting directly on the device (1) that displays a time-dependent value.
