Senator Perpetual Calendar

It's considered one of the greatest challenges of the watchmaker's art: The Perpetual Calendar indicates not only the weekday, date and month, but leap years as well. The Senator Collection lends this sophisticated complication a face as elegant as it is contemporary.

The dial of this elegant timepiece presents each of the displays as part of a clear and harmonious whole. Along with the Panorama Date, weekday, month and leap year displays, the Senator Perpetual Calendar shows the moon phase in a separate window at 7 o'clock. Every detail is executed with elaborate care: from the galvanic starry sky to the domed moon relief.

The calendar functions  –  the Panorama Date at 4 o'clock, weekday at 10 and month at 2 o'clock  –  are easily set using quick correctors on the case. A practical universal corrector makes it possible, in addition, to synchronise the linked displays with the leap year, which is indicated by a red dot above the centre of the dial.

When setting the watch a clever reset-to-zero function allows one to synchronise the watch's second hand with the standard time. Contrary to other zero-reset mechanisms the seconds hand is linked to neither the winding shaft or the crown - thus the balance keeps moving and the movement continues to run, which reduces material wear and tear.
