Craig Duling is chairman of Heritage Management Services, Inc., and oversees the firm’s overall strategic direction. An avid antiquarian horologist, Craig Duling maintains the website Heritage Pocket Watch at http://www.heritagepocketwatch.com. His site features numerous rare and collectable antique pocket and wrist watches, which are part of a collection built on a four-decade passion for acquiring timepieces. One of the most remarkable watches is a circa-1890, 18-karat rose gold Jules Jurgensen minute repeater split-second chronograph, which has a 60-hour minute register.
Born in the early 1800s in Switzerland, the pioneering watchmaker Jules Jurgensen grew up in Copenhagen. A third-generation horologist, he followed in the steps of his grandfather, who had built a strong business relationship with the celebrated watchmaker J. F. Houriet and married his daughter. Settling in Geneva in 1836, Jules Jurgensen put the imprint “Copenhagen” on his watches for many years. He achieved a number of noteworthy patents, including one in 1867 for novel methods of setting the hands of the watch through moving the bow backward (open face) or forward (hunting case). Jurgensen-style cases were widely imitated in the United States throughout the late 19th century.
