The Cartier Ceinture Trinity (Reference 81045) is a highly collectible vintage timepiece from the 1980s and 1990s that perfectly showcases the Maison's legacy of avant-garde horological design.

The model is named after the French word for "belt" (ceinture), inspired by its distinct square, octagonal-stepped case shape that mirrors a classic belt buckle. What distinguishes this rare "Trinity" variant is its layered case framework constructed from three beautifully distinct tones of 18k gold—yellow gold, white gold, and rose (pink) gold. This design choice pays homage to the legendary multi-tonal metal technique popularized by the Cartier Trinity Ring.

• • Case Width: Measures 26.5mm to 27mm (historically considered the large model size for this line), giving it a commanding flat profile and elegant wrist presence. 

  • Integrated Crown: Features a unique octagonal winding crown cleanly recessed into a protective slot within the stepped bezel architecture.

The Dial and Paris Signature

The face of the watch maintains all of the essential heritage codes of classic Cartier watchmaking. It highlights a stark white or light ivory dial decorated with crisp black Roman numeral hour markers and traditional blued-steel sword hands.

Crucially, the presence of the "Paris" signature just below the 6 o'clock marker signifies that the timepiece belongs to an era when the watch was sold directly out of the historic Cartier Paris Boutique. This inscription is a coveted attribute for vintage watch collectors, elevating its desirability compared to later variations signed "Swiss Made".
