Vintage 1990s Cartier Must de Cartier 21 reference 1340 quartz watch in 28mm stainless steel featuring a white silvered dial, rotating bezel with engraved Roman numerals, blued steel sword hands, sapphire cabochon crown, and integrated stainless steel bracelet, in very good condition. Total bracelet length 6 inches.

Cartier is one of the most storied luxury houses in the world, founded in Paris in 1847 and recognized today as the pre-eminent authority in both fine jewelry and luxury watchmaking — the creator of the first wristwatch worn in combat, the Santos (1904), and of icons including the Tank, the Pasha, the Ballon Bleu, and the Panthère. The Must de Cartier line was introduced in 1973 as Cartier's deliberate entry into a more accessible price segment, using vermeil and steel construction to bring the Cartier design language to a broader audience without compromising the brand's design identity — a strategy that proved enormously successful and helped Cartier establish itself as the dominant luxury brand of the late 20th century. The Must de Cartier 21, introduced in the late 1980s and produced through the 1990s as reference 1340, is one of the most design-forward pieces in the Must lineup — its rotating Roman numeral bezel, which displays the 12, 9, 6, and 3 o'clock positions as full engraved numerals while the clean, uncluttered inner dial focuses entirely on the blued steel hands, represents a bold inversion of conventional watch dial design that feels as contemporary today as it did at introduction. The 21 designation references the 21 Place Vendôme address of the Cartier Paris flagship — a detail that connects the watch directly to the Maison's most prestigious heritage.

The 28mm stainless steel case presents the Must 21's characteristic soft-cornered round profile with an integrated bracelet that flows seamlessly from case to wrist through a series of rounded pill-shaped links — a construction that gives the watch a sportier, more integrated silhouette than the typical dress watch with conventional lugs. The rotating outer bezel carries the four cardinal Roman numerals in deep engraving across its full brushed-steel surface, allowing the wearer to set a second time zone or track elapsed time independently of the inner dial. The inner white silvered dial is deliberately minimal — a fine minute track ring around its perimeter and the "Must de Cartier" signature at center being the only elements, with all hour indication provided by the bezel above. The blued steel sword hands are the quintessential Cartier detail, appearing across virtually every reference the Maison has produced for over a century, providing a warm blue contrast against the cold steel case and silvered dial that identifies this watch as Cartier at a glance. The black faceted sapphire cabochon crown at 3 o'clock adds Cartier's signature jeweled crown detail that connects the Must 21 directly to the brand's fine jewelry heritage.
