Perpetual calendars rule at SIHH

Most perpetual calendars also come with a moon-phase display; some might add further detail to the dial with a second time zone or an equation of time, an indication of the difference between true solar time and mean solar time Which brings us to SIHH 2019, where the perpetual calendar is very much in evidence One characteristic of the perpetual calendar is its tendency to "Occupy" the dial with its many subdials and apertures, with the advantage that these multiple indications quickly lend the perpetual calendar watch a sough-after "Technical" appearance though not without the touch of romanticism that comes with a moon-phase display.

Rather than overload an already busy dial with additional information, and compromise legibility, the perpetual calendar is typically a complication that suffices unto itself and one whose harmonious design, done properly, is worthy of admiration So it makes sense that perpetual calendars were everywhere to be seen at SIHH, now that markets appear to be newly receptive to this type of sophistication Among the models on show were reissues such as the Langematik Perpetual which A.

Lange & Söhne is offering in honey gold, and IWC's Big Pilot's Watch Perpetual Calendar Spitfire, driven by an in-house manufactured movement Even the newly launched Code 11.59 by Audemars Piguet collection has its Perpetual Calendar. . Source
