ALL MECHANICAL "Digital" WAtch.

De Grisogono - Meccanico DG

The mechanically operated digital display of the second timezone shows tens of hours, single hours, tens of minutes and single minutes, all displayed by mobile microsegments driven by an assemblage of 23 cams connected to a set of gears and a triggering and synchronization system. The time information is displayed by an array of 23 horizontally and vertically positioned microsegments. Vertical segments are 9 mm high and weigh at most 25 milligrams while the horizontal segments measure 2.90 mm in length and weigh only 10 milligrams. The segments have four faces: two opposing visible faces fitted with colored strips and two opposing unmarked faces. Time changes are effected by 90° rotations of the required segment or segments. Involving one to twelve segments, time changes are lightning fast.

Not something I usually show on but you have to admit for old school analog technology this is outstanding. If your into this then you may be interested in the Urwerk 202, which also has slightly different type of movement and method of displaying the time.

The revolving satellite complication displays time using telescopic minutes hands operating through the middle of three orbiting and revolving hours satellites. The telescopic minute hands precisely adjust their length to follow the three sectors marking the minutes.
