The present watch evolved from a long tradition of horological excellence, a masterpiece produced by a master watch brand. Long before the advent of the wristwatch, pocket watches were the sole transportable mode to tell time, ranging from the basic time only, to complicated timepieces, like the Quantiême Perpetéuel, the pocket watch in the 19th century, and early 20th century made the man. Today, while they are seen more as a novelty item, they are the precursor to what today is modern and exciting. The perpetual calendar complication is found on many of the most important wristwatches today, including Audemars Piguet’s classic the Royal Oak.

The present example is in lovely original condition, and accompanied by its original certificate of origin and presentation box. Sold in Switzerland in 1983, the watch make a superb example of a complicated pocket watch for sophisticated collectors.
