Most of the world is happy to accept the Gregorian calendar and the need for leap years—but the Bovet Récital 20 Astérium is having none of that. Since the Earth actually spins around the Sun once every 365 days, 6 hours, 9 minutes and 9.77 seconds (or 365.25 days) the calendar needs to catch up to the sky every four years, hence the leap year. A watch will require manual or mechanical adjustment to account for the extra day. In the case of an annual calendar, you reset the watch each February. A perpetual calendar will adjust for February’s shifting length through mechanical gymnastics every four years. But the Bovet Récital 20 Astérium dispenses with the pretense and simply counts time as it is—setting its annual calendar by the stars, not Pope Gregory XIII. The result is both simple and complex.
