The Senator Diary from Glashütte Original was a groundbreaking watch when it was first introduced. It was the first mechanical watch to offer an alarm that could be set up to 30 days in advance. The watch is powered by the impressive Caliber 100-13, which consists of 631 components, including 340 in the diary appointment module alone. When the set alarm time arrives, it will ring for up to 80 seconds. The design of the watch is elegant and balanced, with two crowns and a pusher on either side of the case. The right side operates the Panorama Data display at 3 o'clock, while the diary alarm can be found at 9 o'clock with a subtle arrow at 6 o
