The Senator Excellence Perpetual Calendar has a 42mm case, with brushed and polished surfaces, as well as the same display for the perpetual calendar - Panorama date at 4 o’clock, moon-phase at 8 o’clock, day-of-the-week, month and leap year at respectively 10, 2 and 12 o’clock. And finally, central hands for the hours, minutes and seconds. What changes is the metal in which the case is crafted; here 18k white gold - usually, the Senator Excellence collection is only available in steel or 18k red gold.
Then is the dial, in matte grey. It has been partially opened in the centre and around the indications to reveal the main plate of the perpetual calendar module. This plate is decorated with an elaborate guilloche decoration, crafted by hand in the watchmaker’s own dial manufactory in Pforzheim. This plate is partially opened to reveal the interplay of the calendar discs.
The Glashütte Original Senator Excellence Perpetual Calendar Limited Edition is powered by the in-house Calibre 36-02 automatic movement, which is visible through the sapphire case back. Offering an impressive 100 hours of power reserve, it features 43 jewels and oscillates at 28,800vph. In true German style, the movement is beautifully decorated and features a Glashütte three-quarter plate with stripe finish, bevelled edges, polished steel parts, and a skeletonised rotor with 21ct gold oscillation weight.
