A Glashütte Original Senator Excellence Perpetual Calendar Limited Edition

There is good reason to consider the perpetual calendar one of the most challenging complications in the art of watchmaking Thanks to its sophisticated mechanism it displays, along with hours, minutes and seconds, the day of the week, month, moon phase and leap year - all the while taking the lengths of the different months into account In theory, at least, no manual correction will be required until the year 2100.

Two characteristic complications have been added, the Panorama Date and the exquisitely crafted moon phase In terms of colour, too, the Senator Excellence Perpetual Calendar - Limited Edition is anchored firmly in the 21st century Set within a 42mm white gold case, the matte grey dial ring with rhodium plated and polished index appliques and the galvanic grey module cover encounter blue accents.

Among the latter are the dark blue Louisiana alligator leather strap, traditional blued hands, the moon phase display's galvanic blue night sky, along with the printed blue minute numerals on the railroad chapter ring, and the leap year indicator. . Source
