The Glashütte Original Senator Perpetual Calendar unites a high-complication movement with a peaceful design language. Driven by the caliber 100-02, the perpetual calendar data is shown through dial apertures, incorporating the signature 'big date' and a subtle leap year indicator situated below the logo at 12 o'clock. Reference 100-02-25-05-06 is fitted with a rubber strap and pin buckle, 100-02-25-05-04 with a rubber strap and folding clasp, and 100-02-25-05-53 with a rubber strap and short folding clasp.
