The new Glashütte Original Senator Excellence Perpetual Calendar offers exceptional legibility, every detail has been honed to perfection by experienced artisans in the watchmaker's own dial manufactory. The curve of the moon phase at 8 o'clock echoes the gently sweeping lines of the case, while the domed moon in relief is set off by a starry, galvanic blue sky. The Panorama Date at 4 o'clock, the weekday and month windows are presented, as in a passe-partout, in a softly curved frame. For the leap year one need only glance at a separate display beneath hour 12. The hand moves counter-clockwise across a scale of 1 to 4, ensuring unmistakable clarity for every year, not just the clearly marked leap year. It features a 42 mm diameter case, available in satin-polished stainless steel or red gold, and is water resistant to 50 meters. The heart of the Senator Excellence Perpetual Calendar beats Calibre 36 automatic movement. An innovative silicon spiral enables extreme precision, while a single spring barrel ensures a power reserve of more than 100 hours.
