Square ring by Chopard, in 18-carat white gold, set with 45 diamonds

In 1860, a 24-year-old son of a farmer, Louis-Ulysse Chopard (1836–1915), established the L.U.C. company — now known simply as Chopard, rather than by the founder’s initials — in Sonvilier, Switzerland. His initial work evolved from making mechanical movements to building the watches themselves, concentrating on making the pocket watch slimmer to carry for everyday use while also ensuring it was precise and reliable.

Early successes for Chopard included providing watches for the punctuality needs of the Swiss Railway Company. Recognizing the international market for Swiss watchmaking, Chopard traveled across Europe and Russia, with Czar Nicholas II becoming a client in 1912.

Chopard’s son, Paul-Louis, took over after Louis-Ulysse’s death in 1915 and expanded the business to La Chaux-de-Fonds. In 1937, the company relocated to the watchmaking center of Geneva, where they could mark their work with the prestigious Geneva Seal. (Paul-Louis’s son, Paul-André, took the reins in 1943.) Business thinned in the postwar years, and Paul-André’s sons declined the opportunity to take over for their father.

In 1963, Chopard was acquired by German goldsmith and watchmaker Karl Scheufele III and his wife, Karin. Under their ownership, Chopard added jewelry to its offerings. The popular Happy Diamonds wristwatch debuted in 1976 — it launched a collection, which now features bracelets, rings and other items. The distinctive watch sees dozens of glittering diamonds, loosed from their settings, moving freely around the dial.

The story goes that the in-house designer Ronald Kurowski was inspired by the kinetic glimmers of sunlight on a waterfall in the Black Forest. He would then develop the innovative system for the Happy Diamonds timepiece that he hoped would essentially mimic his experience in the woods.

A young Caroline Scheufele — Karl and Karin’s daughter, who would later become copresident and artistic director — led the introduction of a Happy Diamonds jewelry line in 1985, with her design for a playful clown pendant with a belly full of jittering precious stones. Subsequent lines and accessories such as the Happy Dreams bracelet, Happy Hearts collection and the Happy Sport watches further enhanced Chopard’s range of dynamic adornment.

The Scheufele family-run company continues to be synonymous with excellence in timepieces, such as its role as the official timekeeper for the Grand Prix de Monaco Historique, creating all of its movements in-house. And Chopard is constantly developing its wares, from sunglasses and fragrances to recent introductions of high-end handbags.
