We present the Cartier watch model Must Rondé, a small, classic-cut women's watch with a round case of ø27mm, made of Vermeil, a silver base covered with yellow gold plating, very popular at that time. Its dial stands out thanks to its white color and the numbers engraved in black, crowned by metallic blue hands, characteristic of the French firm. The sapphire embedded in the crown, used in all Cartier watches as a mark of distinction and originality, is preserved in perfect condition. In addition, it has its original red strap, with a gold folding clasp, to give a wonderful second life to this Cartier watch for women. This vintage Cartier watch has been used, but its condition is good, with signs of use visible to the naked eye.
