The Senator Diary debuted as the first mechanical timepiece capable of setting an alarm up to 30 days in advance, powered by the 631-component Caliber 100-13. It features a dual-crown design with an 80-second alarm and a sophisticated date-tracking mechanism that handles month-end transitions automatically. Available in references 100-13-04-04-02 (pin buckle), 100-13-04-04-04 (folding clasp), and 100-13-04-04-50 (short folding clasp), all paired with alligator straps.
