The 42 mm Senator Chronometer is the first officially certified chronometer from Glashütte Original. Precise to the second, German chronometers must pass a battery of performance and accuracy tests housed within their own cases. Certification is administered by the State offices for weights and measurements of Thuringia (LMET) and Saxony (SLME).

The Senator Chronometer is powered by the manual winding caliber 58-01, and features a stop-seconds/reset mechanism for precision time setting.
