When the second becomes an important moment, the chronometer represents a very accurate watch. In the past, the accuracy of time was absolutely necessary in the field of navigation and aviation. Also today, an impartial and independent body uses the same standard measurement procedures to test whether a watch meets the accuracy requirements of the year. A watch is eligible to be called a ‘chronometer’ only if it is certified by an authorized body. Needless to say, all of Glashütte’s hand-finished movements meet these strict criteria: and the sensor chronometer is the first watch to have this official certification.
The Senator chronometer is equipped with the redesigned caliber 58. cal. A new stop-second / reset mechanism makes it easy for the wearer to adjust the time: pull the crown to stop the time, the second hand jumps back and maintains the initial position, and the minute hand moves to the next minute mark. When you turn the crown to adjust the time, the minute hand does move in accordance with the minute scale: this mechanism ensures that the minute hand and second hand are in the correct position.
