Cartier Watches
Must 21 Model

A revolutionary concept in the 1970s, when they were developed by Robert Hocq, Cartier’s “Musts” make up a range of accessories including perfumes, leather goods and watches.

Created for a generation that was passionate about a new kind of luxury, the range defined its era.

The elegant and timeless Must 21 watch features a round casing and a gold or steel bracelet.

This model plays on the elegance of Roman numerals directly engraved into steel, with a winder adorned with a small sapphire cabochon, the distinctive symbol of the house of Cartier.
