fiogf49gjkf0d

Glashütte Original introduced its first automatic calibre featuring a power reserve of up to 100 hours at a frequency of 4 Hertz (28,800 A/h). This high degree of autonomy is achieved with the use of only one spring barrel, developed specifically for this purpose. The new calibre 36 is fitted in Glashütte Original Senator Excellence watch and supported with an innovative silicon balance spring. That´s a premier for Glashütte Original and a premier in Glashütte, since never before a wristwatch manufactured there was equipped with silicon balance spring. The high-tech material renders the ultra-thin spring immune to changes in temperature and to magnetic fields, its oscillation is extremely isochronous. A bi-directional winding mechanism ensures that the watch remains within the optimal charge range; a guarantee for excellent rate results.
