The heart of the Senator Diary is the Glashütte Original caliber 100-13, which combines the caliber 100-03 with the extraordinary new diary appointment module for total of 631 components (the diary appointment module alone consists of 340 components), all but a handful of which are designed, manufactured, finished and painstakingly assembled in the Glashütte Original manufactory.

A superb example of the art of engineering at Glashütte Original, the ingeniously interlocking components permit the wearer to set an appointment beyond the end of the month, even when a manual correction of the date is required; any change in date at the end of the month is passed along to the alarm mechanism, obviating the need to reset the alarm. A third spring barrel built into the module ensures that even if the watch runs down, the alarm remains wound.

The Caliber 100-13 automatic movement exhibits further evidence of excellence in fine mechanical watches from Glashütte Original, including a divided three-quarter plate with Glashütte ribbing, polished steel components, beveled edges and blued screws. These exquisite finishings are easily visible through the sapphire crystal case back.
