Cartier Tank Louis “Paris” 18K Yellow Gold
Ref. 78086 GM / LM (Large Size) – 1970s
Presented here is an elegant Cartier Tank Louis “Paris” from the 1970s, reference 78086, in the highly desirable GM / LM large size. A timeless expression of Cartier design, this piece combines refined proportions with a beautifully preserved Paris dial and classic mechanical elegance. With a strong case, documented Cartier service history, and a fresh service in 2026, it offers both collectability and reliability.
Dial
The watch features a Paris-signed dial in outstanding condition, with no cracks and an exceptionally clean appearance for its age. The glossy lacquer finish remains remarkably well preserved, offering strong contrast against the Roman numerals and minute track while contributing to the watch’s crisp, balanced aesthetic.
The blue steel sword hands have naturally aged over time, developing a warm mustard tone—a characteristic patina sometimes seen on vintage blued hands and a detail appreciated by collectors of original watches.
Case
The solid 18K yellow gold case is in great condition, retaining the elegant geometry that defines the Tank Louis design. In the GM / LM large size, it offers excellent wrist presence while remaining unmistakably refined.
The iconic sapphire cabochon crown, set with a deep blue sapphire, completes the classic Cartier silhouette.
Movement
Inside beats the manual-wind Cartier Calibre 78-1, a slim and reliable movement that reflects Cartier’s dedication to mechanical elegance.
The watch comes with Cartier paperwork from a service performed in 2000, adding valuable historical documentation. It has also been freshly serviced by our watchmaker in 2026 and is working excellent, ensuring smooth winding and dependable performance.
Strap & Buckle
The watch is fitted with a handmade black leather strap crafted in Belgium by our brand, complementing the classic character of the piece.
It is paired with a gold-plated pin buckle from Cartier, maintaining an elegant and understated finish.
Why This Watch Stands Out
The Cartier Tank Louis Ref. 78086 is one of the most elegant expressions of vintage Cartier design. The combination of its rare GM / LM case size, beautifully preserved Paris dial, naturally aged steel hands, strong gold case, and documented Cartier service history makes this a particularly attractive example.
Freshly serviced and ready to wear, it represents a refined balance between collector value and timeless everyday elegance.
