While the Tourbograph
Perpetual naturally drew a lot of attention, the sleeper hit from SIHH could be the 1815 Annual Calendar. While this complication does not have the same technical complexity as a perpetual calendar, what it gains instead is a very elegant, slim profile, and a day-to-day usability that’s undeniable. The case is 40.0mm wide, and a scant 10.1mm thick, rendering it supremely comfortable on the wrist. The annual calendar is also very user-friendly; the pusher at 2 o’clock is used to advance all the calendar indications at the same time, such that you need not worry that the watch is not automatically wound as complex calendars tend to be. The only adjustment you’ll need to make is once a year on March 1st, as the annual calendar treats February as a 30-day month. The rest of the time, the 1815 Annual Calendar can be quickly wound to its 3-day power reserve, and the 2 o’clock pusher will be used to set the calendar correctly, without needing to adjust the day, date, month or moonphase separately. It’s German pragmatism at its best, all in a beautifully finished and accessible timepiece.
