Introduced almost 20 years ago, the Glashütte Original perpetual calendar is distinguished by its functional and legible display, with four windows for each element of the calendar. Now at Baselworld 2017 the perpetual calendar has finally received a major upgrade with a new base movement, the Senator Excellence calibre 36, at a minimal price increase of about 5%.
Unveiled last year in time-only form, the calibre 36 is a robust automatic movement that’s destined to become the workhorse movement for the brand. It has a useful four-day, or 100-hour, power reserve, nearly double the 55 hours of the calibre 100 found in the earlier versions of the perpetual calendar. And it also has a silicon hairspring and free-sprung balance.
The perpetual calendar mechanism, however, remains the same. The two-disc, oversized date display remains at four o’clock, with the day, month and moon phase almost symmetrically position in the remaining quadrants of the dial. A small sub-dial at 12 o’clock indicates the leap year.
Available in red gold or steel, the case is 42mm in diameter, while the dial for both is silver-plated with a grained finish. Notably, rather than just being printed, the markings on the dial are laser engraved and then filled with black lacquer.
