The added perpetual calendar functions have been seamlessly integrated into the dynamic design of this efficient timepiece. The disks for both day and month and the typical Glashütte panorama date are displayed in white on a black background resulting in a visually clear and balanced dial. Nothing gets in the way of the dial’s legibility at night either; the hour numerals, and the blued hour, minute, and second hands are inlaid with the luminescent material SuperLumiNova.
The Double G logo guarantees a counterbalance on the tip of the second hand. In order to do justice to the dynamic character of the timepiece, designers at Glashütte Original decided to create a leap year display using a hand at 12 o’clock: when it points to the red L, it is currently a leap year. In addition to a perfectly legible dial, rate precision is vital in a pilot’s watch. Inside the Senator Navigator Perpetual Calendar, automatic manufacture Caliber 100-07 guarantees this precision.
Automatic manufacture Caliber 100-07 commands a power reserve of more than 55 hours (+/- 10%) and sports a reset mechanism that allows for easy synchronization of the second hand with a time standard. Unlike other reset mechanisms, the second hand here is neither connected to the winding stem nor the crown. As a result, when the crown is pulled out the balance remains in oscillation and the movement continues to run, significantly reducing material stress. The reset mechanism is activated by pressing a separate button on the side of the case at 8 o’clock.
A soft, used-look calfskin strap with stainless steel buckle provides the perfect finish to the pilot look of the Senator Navigator Perpetual Calendar.
