Cartier Must De Cartier 21, Ref. 9010, Cal. 81, 1989

This 1989 Cartier Must de Cartier 21 Ref. 9010 is the larger 31 mm version, with a wide Roman-numeral bezel and an original integrated two-tone bracelet. Slim blue hands stand against a light central dial, with a blue cabochon crown repeating their color. Cartier Cal. 81 provides quartz timekeeping, and the bracelet is sized for an 18.5 cm wrist.

Roman-Numeral Bezel and Blue Hands

Engraved gold-tone Roman numerals sit against the broad brushed steel bezel. Inside this ring, the light dial has a restrained layout with printed Cartier branding and slim blue hands. The contrast between the pale center, darker steel ring and gilt numerals gives the display depth without additional dial decoration.

The Larger 31 mm Case

The rounded case combines stainless steel and gold, with brushed surfaces and warm detailing. It measures 31 mm across and 34 mm lug to lug. The short overall length keeps the larger version compact while leaving the wide bezel visually prominent.

A blue cabochon is set into the crown. The used exterior retains visible signs of age, with the brushed texture continuing across the case and bezel.

Original Integrated Bracelet

The case flows directly into repeating rounded bracelet links, with fine gold stripes running through the center. This original two-tone bracelet forms a continuous outline with the watch head rather than meeting conventional strap lugs.

The stated wrist size is 18.5 cm. The bracelet remains part of the original watch components, preserving the complete case-and-bracelet design.

Cartier Cal. 81 Quartz

Cal. 81 is a quartz movement, supplying electronic timekeeping to the central analog display. It provides the watch’s timekeeping function without a daily hand-winding routine.

The watch is fully serviced and fully operational, with its original watch components retained. It comes with a 12-month warranty.
