Glashütte Original Senator watches

The Glashütte Original Senator is the brand's range of mechanical watches that pair technical complexity with traditional design, running from the time-only Senator Excellence through big-date Panorama Date models, chronographs and the Senator Cosmopolite world-timer to several tourbillons. Current models measure 40 to 44 mm.

Most current Senator models are automatic. The hand-wound exceptions are the Senator Chronometer, the Senator Chronometer Regulator, the Senator Chronometer Tourbillon, the skeletonised Senator Manual Winding and Senator Moon Phase editions, and the Alfred Helwig Tourbillon 1920. Its name honours the Glashütte watchmaker who invented the flying tourbillon in 1921; the Senator Tourbillon Edition Alfred Helwig carries it too.

Calibre 36, the Senator Excellence movement, was unveiled in 2016 in time-only form: an automatic with a silicon hairspring, a free-sprung balance and a 100-hour power reserve. In 2017 it went into the 42 mm Senator Excellence Perpetual Calendar, replacing the calibre 100 of the earlier perpetual calendars, which runs for 55 hours.

That split runs through the range. The 40 mm Senator Excellence, Excellence Panorama Date and Excellence Panorama Date Moonphase use versions of calibre 36, while the older Senator Panorama Date, Senator Perpetual Calendar (calibre 100-02) and 44 mm Senator Observer use versions of calibre 100. The 42 mm Senator Chronograph Panorama Date (calibre 37-01) is a flyback chronograph with a column wheel and a big date; its Capital Edition came in runs of 100 in steel, 25 in red gold and 5 in platinum. The Senator Cosmopolite is a 44 mm world-timer with calibre 89-02, and the platinum Grande Cosmopolite Tourbillon measures 48 mm.
