Cartier Tank Américaine Jumbo Ref. 1740

Partially verified

This Cartier Tank Américaine Jumbo, reference 1740, is an automatic wristwatch characterized by an elongated, curved 18k yellow gold case measuring 44 by 27 millimeters. It features an eggshell-colored dial with black Roman numeral indices, a central date window at the 6 o'clock position, and blued steel hands. A blue sapphire cabochon is set into the crown. The watch is powered by a mechanical automatic movement, contrasting with more common quartz variants of the model. The piece is fitted with a brown leather strap secured by an original 18k yellow gold Cartier buckle. The Tank Américaine design, introduced in the late 1980s, draws inspiration from the 1920s Tank Cintrée.

Object description

Case and Dial Design

The Cartier Tank Américaine Jumbo features an 18k yellow gold case designed with a distinct elongated and curved profile. Measuring 44 by 27 millimeters, the case is specifically engineered to conform to the curvature of the wearer's wrist. The dial, finished in an eggshell hue, displays black Roman numerals and is marked with the 'Swiss Made' inscription at the bottom.

A notable detail on the dial is the hidden Cartier signature integrated into the Roman numeral VII. The time is displayed via blued steel hands, which complement the blue sapphire cabochon stone set into the winding crown. A date aperture is positioned at the 6 o'clock mark, enclosed within the inner rectangular minute track.

Movement and Functionality

Unlike many standard versions of this model line that utilize quartz movements, the reference 1740 houses a mechanical automatic caliber. This feature is highlighted as a significant element for collectors of mechanical horology.

The auction description reports that the movement has been fully inspected and serviced by a watchmaker.

Provenance and Model History

The Tank Américaine model was first introduced by Cartier in the late 1980s. Its aesthetic is historically inspired by the Tank Cintrée, a model originating in the 1920s noted for its slender, curved geometry. The combination of this historic design language with a mechanical movement defines the character of the reference 1740.

According to the provided specifications, the watch carries the serial number 715xxxx, which is associated with production in the early 2000s. The watch is accompanied by an original 18k yellow gold Cartier buckle attached to a brown leather strap and comes with a handcrafted leather travel case.
