The Cartier Diabolo Ref. 1440 is a distinctive and lesser-seen expression of Cartier’s design language – combining playful elegance with refined detail. Introduced in the 1990s, the Diabolo stands apart with its round case and signature cone-shaped crown tipped with a deep blue sapphire cabochon. Crafted in 18k yellow gold, the watch features a clean white dial with classic Roman numerals, blued steel hands. The overall design is both whimsical and precise—true to the maison’s tradition of blending formal elegance with a touch of the unexpected. Powered by a reliable quartz movement and sized for understated presence, the Ref. 1440 captures the essence of Cartier’s more unconventional creative period. This very version is in beautiful condition with only light scratches to the case, but a lightly visible bump to the case. It’s accompanied by the fullset.
