A watch includes a quartz-controlled electronic drive circuit for the control of the clockwork mechanism of a pointer-driving system for analog display of the time of day, and a digital read-out unit and control circuit for the display of additional data such as month, day of the month, day of the week, and the like. A synchronizing unit is located between the analog and digital systems to provide a synchronous link between the time of the day and the digitally displayed data. This synchronizing unit is coupled with the pointer-driving clockwork mechanism and generates a synchronizing pulse which is derived from the clockwork, preferably at a rate of one pulse per 24 hours. The synchronizing pulse is fed into the display control circuit to synchronously advance the digital read-out of the month, day of the month and day of the week, for example.
