Cartier: The King's Jeweller — Baignoire, Santos & The French Art of Watchmaking
The Direct Answer
Cartier is a French luxury watch and jewellery brand founded in Paris in 1847, now part of the Richemont Group. It is the world’s most famous jeweller and one of the most important watchmakers — the brand that invented the men’s wristwatch with the Santos in 1904, designed for Brazilian aviator Alberto Santos-Dumont. Its most iconic watches are the Santos (square case, exposed screws), the Tank (rectangular, inspired by WWI tanks), the Baignoire (oval case), and the Ballon Bleu (round with floating crown guard). Cartier is best purchased for the pleasure of ownership and cultural significance rather than investment value.
The King’s Jeweller, the Jeweller of Kings
Cartier was founded in Paris in 1847 — not in Switzerland, but in France. This French origin gives Cartier a distinctive character: more artistic, more fashion-conscious, more attuned to the rhythms of Parisian luxury than the precision-engineering culture of Geneva or the Jura.
The Prince of Wales — later King Edward VII of England — called Cartier “the jeweller of kings and the king of jewellers.” Cartier has held royal warrants from the courts of Britain, Spain, Portugal, Russia, Siam, Greece, Serbia, Egypt, and Albania. Its clients have included virtually every crowned head of Europe, every maharaja of India, and every Hollywood star of the 20th century.
Cartier is now part of the Richemont Group. Beyond watches, Cartier produces pens, eyewear, leather goods, briefcases, lighters, and accessories — one of the world’s most complete luxury houses.
The Santos: The Watch That Started Everything
In 1904, Louis Cartier designed the Santos for his friend Alberto Santos-Dumont — the world’s first purpose-built men’s wristwatch. Its square case with rounded corners, exposed screws on the bezel, and integrated bracelet established a design language unchanged for 120 years. The Santos Diamond — with its diamond-pavé bezel — represents the ultimate expression: the world’s first men’s wristwatch elevated to fine jewellery.
The Tank: Inspired by War, Perfected for Peace
In 1917, Louis Cartier designed the Tank — a rectangular watch inspired by the aerial view of WWI Renault FT tanks. Worn by Andy Warhol, Princess Diana, and Jackie Kennedy, it is the watch that appears most frequently in fashion photography and on red carpets. Restraint is the highest form of luxury.
The Baignoire: The Oval Masterpiece
The Baignoire — French for “bathtub” — is Cartier’s most distinctive case form: a tall oval, narrower at the top and bottom than at the sides. Available in plain (smooth polished bezel, white dial, black leather strap) and diamond versions (diamond-pavé bezel covering the entire oval edge).
The Pasha: Born from a Governor’s Request
In the 1930s, the Pasha of Marrakech commissioned Cartier to create a water-resistant watch for swimming. Cartier’s solution: a screw-down crown cap attached by a chain. Relaunched commercially in 1985, the Pasha remains one of Cartier’s most recognisable designs.
Cartier’s Design Philosophy: Art Above All
Cartier prioritises beauty above all. Every Cartier watch is designed as an object of art before it is designed as a timekeeping instrument — the Santos’s exposed screws, the Tank’s architectural rails, the Baignoire’s oval form, the Ballon Bleu’s floating crown guard. You buy a Cartier for how it looks, how it feels, and what it represents.
Cartier Value Retention in 2026
Cartier watches retain approximately 70–80% of retail value after several years. The Tank Louis Cartier in gold and the Santos in steel are the strongest performers. Cartier is best purchased for the pleasure of ownership — it is a statement of taste and refinement, not an investment vehicle.
