Senator Diary

Presenting a world first. No mechanical watch has ever made it possible to set an alarm up to 30 days ahead of time - until now.

The heart of the Senator Diary is the Glashütte Original Caliber 100-13 including 631 components (the diary appointment module alone consists of 340 components). When the set date and time arrives, the alarm rings – for up to 80 seconds.

 

The Senator Diary is beautifully balanced, with two crowns positioned directly opposite each other on either side of the stainless steel case, each flanked by a pusher. The crown and pusher on the right operate the compelling Panorama Data display, positioned at 3 o’clock.

The eye of the connoisseur is drawn immediately to the diary alarm — a black subdial framed by a German silver ring at 9 o’clock and a gently curving aperture indicated by a red arrow at 6 o’clock.

To set the alarm, first select the date, referring to the diary alarm window positioned within the subdial at 10 o’clock. Press the pusher positioned at 8 o’clock until the letter ‘d’ appears in the window. Turn the 10 o’clock crown until the red and silver pointer selects the correct date from Arabic numerals 1 to 31. 

To set the time, press the pusher once more; the letter ‘h’ appears. Turn the crown to select the time, referring to the aperature at 6 o’clock, from quarter-hour intervals from 00.15 to 24.00 hours. To set the alarm, press the pusher once more to bring the alarm symbol (a bell) into view, then turn the crown to wind the alarm. When the set date and time arrives, the alarm rings – for up to one minute.

To stop the alarm (or to cancel one set previously), press the 8 o’clock pusher until the ‘alarm off’ symbol appears in the window (a black line struck through the bell).

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 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.

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.
