The world's first "hybrid mechanical-digital watch"

Consisting of 651 pieces (and no IC chips), the Di Grisogono Meccanica DG is the world's first "hybrid mechanical-digital watch." Slated to sell for $199,977 just 177 of these unique timepieces will be made to celebrate the 50th anniversary of the Geneva-based horloger. Billed as the most complicated digital-analog timepiece in the world, the digital display is actually mechanical, with rolling tubes forming the digital segments.

As detailed in horloger's press release: 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.
