Cartier Must Tank Trinity
Ref. 3 66001 — Manual winding — 21 x 28 mm
Elegant, iconic, and deeply symbolic, the Cartier Must Tank Trinity blends the geometric DNA of the Tank with the emblematic codes of the Trinity motif: yellow gold, rose gold, and white gold. This subtle combination makes this model one of the most poetic and refined in the Must collection, embodying harmony, balance, and sophistication.
This example, in very good condition and recently serviced, is distinguished by its case, which remains true to the Tank aesthetic: straight lines, perfect proportions, integrated lugs, and a silhouette of absolute purity. Its dimensions of 21 x 28 mm make it an elegant, discreet watch, ideal for a slender wrist, while retaining the timeless presence characteristic of Cartier creations.
The Trinity signature appears delicately on the case, evoking the union of three golds so dear to the House of Cartier. A subtle yet highly symbolic detail, sought after by collectors and lovers of unique pieces.
The watch comes with a new (non-original) salmon-colored strap, a refined aesthetic choice that adds a soft, luminous, and very contemporary touch to the overall look. This modern contrast enhances the warmth of the case and highlights the elegance of the light Cartier dial.
Powered by a hand-wound mechanical movement, it perpetuates the most authentic watchmaking tradition: a delicate, daily gesture that creates a real link between the watch and its owner.
A discreet icon steeped in history, the Must Tank Trinity is a perfect choice for those seeking a vintage watch full of charm, symbolism and Parisian elegance.
Watch guaranteed for 1 year.
