The new limited edition Senator Excellence Perpetual Calendar from the Glashütte Original Senator Excellence family offers deep insights into the mechanism within thanks to its stunning open-worked dial. Launched in 2016, the innovative Calibre 36 by Glashütte Original sets new standards in terms of precision, stability, running time and beauty. The new special edition takes up this central theme. Limited to 100 pieces, the new model lends the classic perpetual calendar a contemporary appearance.
The central cut-out shifts the centre of attention to the technical aspects of the galvanic grey module cover plate, whose openings reveal the interplay of the calendar discs. An elaborate guilloche decoration adorns the movement’s cover plate, its sweeping lines broken only by individual red jewels. The guilloche decoration is crafted by hand in the watchmaker’s own dial manufactory in Pforzheim. In the process, traditional guilloche patterning tools are used to incise finely drawn geometric figures in the dial. Depending on how the light falls on the dial, the shimmering pattern takes on a very different appearance.
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. The Panorama Date presents its large-format numerals on the same plane and without a vertical separation bar, while silver stars are set off against the moon phase display’s dark blue night sky.
Set within a 42 mm white gold case, the matte grey dial ring with rhodium plated and polished index appliqués 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. Through the sapphire crystal on the back of the watch, one can observe the finely finished 36-02 automatic movement, which features a power reserve of at least 100 hours.
All models in the Senator Excellence family feature exceptional quality with respect to precision, stability, running time and beauty. And all provide proof of this claim in the form of an exclusive certificate confirming that each Senator Excellence timepiece has been thoroughly tested for 24 days in Saxon manufactory. An exclusive online portal also provides each watch’s owner access to comprehensive information regarding the various testing procedures, together with comprehensive test results for the watch.
