With 2012 being both a lucky Year of the Dragon and a leap, it’s not surprising that many of the timepieces introduced at the recent Salon International de la Haute Horlogerie (SIHH) watch fair in Geneva gave major consideration to the calendar — the “annual” versus “perpetual” figuring prominently in the mechanical innovations and aesthetics of many of the exhibit’s most exciting timekeepers. A quick refresher on the functions: an annual calendar on an automatic watch usually needs to be adjusted once per year, at the end of February, to adjust for the month’s fewer days; a perpetual calendar accounts for February’s 28 days and its odd 29th, and needs only a manual nudge every 100 years or so, far beyond the average watch wearer’s needs. Clunky desktop date keepers, meet the competition.
