Cartier Ellipse GM “Paris” Ref. 78091 – Louis Cartier Collection, 18k Yellow Gold (1970s)

A distinctive and elegant creation from Cartier’s creative period of the 1970s, this Cartier Ellipse GM Ref. 78091 from the Louis Cartier Collection reflects the maison’s mastery of refined geometric design. Crafted in solid 18k yellow gold and powered by the manual-wound Cartier calibre 78, this example stands out with its beautifully balanced horizontal Ellipse case and highly desirable “Paris” signed dial.

Well preserved and visually striking, it represents a rare and sophisticated expression of vintage Cartier watchmaking.

The Cartier Ellipse Design

While Cartier is most widely known for icons such as the Tank and Santos, the Ellipse line represents one of the maison’s most elegant explorations of form.

Departing from traditional rectangular shapes, the Ellipse design features soft curves and elongated proportions that create a harmonious silhouette on the wrist. The horizontal orientation of this model gives it a unique presence while maintaining the understated elegance typical of Cartier dress watches.

Produced during the 1970s, this reference belongs to the Louis Cartier Collection, a line dedicated to Cartier’s most refined and traditional watch designs.

Case – 18k Yellow Gold GM

The solid 18k yellow gold case measures 32.5 x 29 mm, making it the desirable Grand Model (GM) or jumbo size within the Ellipse range.

Despite its vintage origins, the case remains very well preserved, maintaining its beautiful proportions and elegant horizontal shape. With a thickness of only 7 mm, the watch wears comfortably and retains the slim profile expected from a classic Cartier dress watch.

Dial – Rare “Paris” Signature

One of the most collectible features of this watch is its “Paris” signed dial, a detail highly sought after by collectors of vintage Cartier pieces.

The dial appears perfectly preserved, showing no signs of cracking, aging, or restoration, and maintains the clean and balanced aesthetic that defines Cartier’s design language.

Its excellent condition greatly enhances the desirability and authenticity of the watch.

Movement – Cartier Calibre 78

Inside the watch beats the Cartier calibre 78, a manual-wound movement known for its reliability and refined construction.

The movement has been serviced and is working excellently, providing accurate timekeeping while preserving the mechanical charm expected from a vintage Cartier timepiece.
