Cartier Tank Française PM Ref. 1820 – The Quintessential Parisian Elegance in Solid 18K Gold

An enduring symbol of French refinement, the Cartier Tank Française PM Ref. 1820 in 18K yellow gold distills more than a century of Cartier design mastery into a compact yet commanding form. Recently serviced by Cartier and presented as a full set with provenance and a two-year Cartier international warranty, this reference represents the maison’s genius for timeless, wearable luxury.

Refined Geometry & Integrated Design

Introduced in the 1990s as a modern evolution of the iconic Tank line, the Française stands apart for its integrated bracelet that flows seamlessly from the case—an unmistakably Cartier innovation that marries form with function.

This petite model features a 20 × 24mm case in solid 18K yellow gold, serial number CC555874, with harmonious proportions and elegant wrist presence. The bracelet, also in 18K yellow gold, is fully integrated and retains Cartier’s unmistakable balance of satin-brushed and polished finishes. With a maximum length of circa 16cm, it embraces the wrist like jewelry yet retains the authority of fine horology.

The crown is adorned with Cartier’s signature blue sapphire cabochon, framing a flawless cream-white dial punctuated by black lacquered Roman numerals and delicate blued steel hands—every detail instantly recognizable as Cartier.

Cartier Quartz Calibre – Serviced & Warrantied

Inside beats the reliable Cartier Calibre 018B Quartz movement, ensuring precise and effortless daily timekeeping. In late September 2025, the watch underwent a complete service by Cartier Brussels, including a professional polish, and is covered by a two-year international Cartier warranty—valid until late 2027. This recent intervention guarantees both beauty and performance.

Complete Provenance – A Collectible Full Set

Few watches arrive with such a meticulously preserved and documented history. This example is offered as a full set, including:

• Large red Cartier presentation box

• Original Cartier Certificat de Garantie International (purchased at Hotel Intercontinental Kinshasa, Congo)

• Cartier service papers with provenance

• Cartier service invoice and warranty (2025)

• Original purchase invoice from the previous owner

• Red Cartier service pouch

Such completeness adds immeasurably to its desirability, ensuring long-term collectibility and market confidence.
