A clock device for timekeeping with an analog display and a time correction unit. The time correction unit uses encoder disks and rotary encoders to convert the angular position of the minute hand and the hour hand to a slave time code. The slave time code is compared to a master time code. A feedback circuit drives the minute hand and hour hand drive-motor(s) until the slave time code equals the master time code. The master time code can be generated from a digital clockworks, or it can be transmitted to the present invention from another clock. The invention can be extended to include a second hand and a time correction unit for a second hand.
