About the Senator family
Senator is Glashütte Original's classic dress collection, with round cases, Roman or Arabic numerals and clear dials. It covers time-only watches, the Panorama Date, chronometers, perpetual calendars and other complications.
The catalog includes models with the caliber 36 family, an automatic with a power reserve of around 100 hours, and the older caliber 100 family, in steel, red gold and white gold. Because the line is broad, confirm the caliber from the reference, check that calendar functions work, and note the strap and buckle.
