The Senator Chronometer is the first officially certified chronometer from Glashütte Original. The term “chronometer” denotes an especially accurate clock or watch such as those used for air and sea navigation in the past.In Germany, wristwatch chronometer certification is administered by the State offices for weights and measurements of Thuringia (LMET) and Saxony (SLME). German chronometers must pass a series of demanding performance and accuracy tests; the exacting German norm requires, in addition, that each candidate for chronometer certification be set to the second and tested in its own case.A novel stop-seconds/reset mechanism allows the wearer to set the precise time with ease. Pulling the crown stops the time display and causes the second hand to jump to the beginning position, where it remains; the minute hand moves simultaneously to the next full minute.When the crown is then turned to set the time, the minute hand stops only on the indication of the full minute, thus always guaranteeing the correct relationship between the minutes and seconds displayed.The layout of the dial recalls that of a pocket chronometer, with subsidiary seconds and power reserve displays along the central axis and the characteristic Glashütte Original panorama date positioned at 3 o’clock.The silver dial provides a rich contrast for the polished, blued sweep minute and pear-shaped hour hands and hand polished arbor. A milled railroad chapter ring encircles the central time display, and the milled Roman numerals add to the classic appearance of this impressive timepiece.Ref. 1-58-01-01-01-01 is fitted with an alligator strap with pin buckle.Ref. 1-58-01-01-01-04 is fitted with an alligator strap with folding clasp.Ref. 1-58-01-01-01-50 is fitted with an alligator strap with shorter folding clasp.
