In the 1970s, Cartier revisited the ingenious idea of a reversible case, reinterpreting it through the unmistakable geometry of the Tank. The result was the Tank Reverso Basculante or Reverso: a refined, architectural answer to the Reverso concept, executed with Parisian elegance rather than sporting intent.
The present example captures that spirit beautifully. Its slim yellow-gold case rotates within its frame to conceal the dial entirely, transforming the watch into a discreet gold bracelet on the wrist. The mechanism operates with satisfying precision, a reminder that this is not merely a design flourish, but a clever piece of engineering rooted in Cartier’s interwar creativity and revived decades later for a new era.
The dial is everything one hopes for in a classic Cartier: crisp white background, bold black Roman numerals, chemin-de-fer minute track, and the elegant “Cartier Paris” signature. The blued steel hands and cabochon sapphire crown add the final, unmistakable touch. Importantly, the case remains nice and well defined, preserving the sharp lines that give the Basculante its distinctive profile.
The watch is further accompanied by its guarantee card dated 13 June 1980, along with booklets and its fitted presentation box.
More than a variation on a theme, the Tank Basculante stands as Cartier’s sophisticated interpretation of the reversible wristwatch, a piece that combines ingenuity, discretion, and timeless design in equal measure.
