Cartier 21 Must de Cartier Gold Plated Steel Quartz Ladies Watch 1990s 28mm ref.W10051F4

Condition: Lightly used

1990s 28mm Cartier 21 Must de Cartier Gold Plated Steel Quartz Ladies Watch ref.W10051F4

Cartier’s Must 21 sits at that interesting intersection where the maison briefly leaned into a sport-luxury identity—integrated bracelet, bold Roman bezel, but still unmistakably Cartier in execution.
This reference, W10051F4, captures that era perfectly with its two-tone construction and compact 28mm case, a size originally marketed to ladies but increasingly worn today as a unisex piece.
Unlike the more formal Tank Must, the 21 feels casual and versatile—something you can throw on daily without losing that Cartier presence.
The applied Roman numerals on the bezel, rather than the dial, remain one of Cartier’s more distinctive design departures from tradition.
