Chopard 171910 L.U.C Regulator 40 Diamonds 18K White Gold Silver Dial LIMITED

The Chopard L.U.C Regulator 40 reference 171910-1001 is a highly uncommon interpretation of the regulator display, executed in 18K white gold with a diamond-set bezel and a silvered dial. Produced circa 2006, this reference belongs to the manufacture-focused L.U.C collection, the line through which Chopard established its modern high horology credentials. The regulator layout separates the indications for hours, minutes, and seconds, giving the watch a distinctly technical character rooted in traditional precision timekeeping and observatory-style regulators. In this configuration, the refined silver dial and gem-set bezel create an unusual balance of mechanical seriousness and formal elegance. Powering the watch is the Chopard caliber 1.98-37089, a manual movement with an impressive extended power reserve that underscores the technical ambition of the piece. Collectors are especially drawn to L.U.C references that combine niche complications with precious metal cases, and this model stands out further for its very limited production of only 25 pieces. The 40 mm case gives it contemporary presence while preserving the restrained proportions expected of a sophisticated dress complication. As a limited white gold regulator from one of the strongest in-house Swiss manufactures of its era, reference 171910-1001 occupies a very narrow and appealing corner of modern collecting. It is a watch for buyers who value discreet rarity, unusual dial architecture, and the depth of finishing and movement quality that define the best of Chopard L.U.C production.
