Description
The story is well enough known to have become a little polished, but it is true: in the early 1970s, Chopard designer Ronald Kurowski watched sunlight break on the spray of a waterfall in the Black Forest and came back with the idea of setting diamonds free. Not fixing them into the dial, but trapping them loose between two sapphire crystals so that they slide and turn with every movement of the wrist. The first Happy Diamonds watch followed in 1976.
Fifty years on, Chopard has reissued it in a form close to the original rather than a modernised interpretation: a cushion case in 18k ethical yellow gold, a black onyx dial, and the stones still skating across it. The 34 mm reference 202299-0001 is the mechanical version at EUR 46,000; a 24 mm quartz, reference 203787-0001, sits below it at EUR 22,800. Neither is a limited edition.
Design
The cushion case measures 34 × 34 mm and 8.53 mm thick in polished 18k ethical yellow gold — Chopard has used exclusively ethically sourced gold across its production since 2018 — under a glareproofed sapphire crystal, water resistant to 30 m. The dial is black onyx, which is the correct choice: onyx gives the diamonds a dark field with no pattern or texture to compete against, so the only thing that moves in the reading is the stones themselves.
Twenty-one free-floating diamonds totalling 1.05 carats sit between the crystals. Hands are gilded dauphine, and there are no applied markers at all — a decision that would look like an omission on any other watch and is obviously right on this one. It comes on a black alligator strap with an 18k yellow gold pin buckle. The 24 mm version reduces the count to nine stones and runs on quartz.

What's Exciting
Happy Diamonds is the rare case of a genuinely original idea in watch design, and it is worth being precise about why. It is not a complication and not a case shape. It is a decision to stop doing something — to stop setting the stones down — and the whole effect follows from that single subtraction. Fifty years later it still has no serious imitators, which in an industry that copies everything is close to remarkable.
Chopard's restraint in the reissue is the right call. The obvious commercial move would have been to enlarge it, brighten it, and fill the dial; instead the brand has gone back to onyx and yellow gold and put a hand-wound movement behind it. The calibre 10.01-C matters more than its specification suggests — a 45-hour manual movement is not a technical statement, but it signals that this is meant as a watch rather than a jewellery object with a quartz module, and at EUR 46,000 that distinction is the one buyers will weigh.
History
Chopard was founded in 1860 by Louis-Ulysse Chopard in Sonvilier, in the Swiss Jura, and built its early reputation on pocket watches and chronometers. The firm was bought in 1963 by the German goldsmith Karl Scheufele III, whose family still runs it — a rare instance of a Swiss house of this scale remaining in private family hands, and the reason Chopard has been able to make decisions such as the 2018 move to fully ethical gold without answering to a group.
The Happy Diamonds concept arrived in 1976 and was quickly extended beyond watches into jewellery, becoming one of the two pillars of the modern brand alongside the L.U.C mechanical collection launched in 1996. The original 1976 watch was a cushion-shaped white gold piece with thirty free-floating diamonds; this anniversary reissue moves to yellow gold and onyx, but the geometry and the idea are the 1976 ones.
