Three Really Nice Perpetual Calendar Watches from BaselWorld 2013

Buben and Zorweg One Perpetual Calendar

Easily one of the hottest complications here at BaselWorld 2013 this year is the perpetual calendar wristwatch. A sophisticated complexity, these watches track so much more than the minutes and hours. One of the top feats of watchmaking, perpetual calendar wristwatches typically hold anywhere from 300 to 600 pieces in their complex movements – and offer indications that are accurate for hundreds of years. They track and display, automatically, the day, month, and date – self adjusting for short months and leap years. Most of today’s perpetual calendar watches typically are built to track time until the year 2100 before needing an adjustment. At that point in time (2100), the leap year that should occur will be skipped so that real time (according to the Gregorian calendar) coincides correctly with solar time. Thus, on March 1, 2100, the average perpetual calendar needs a watchmaker to make a fine correction to the movement.
