The Tank Legacy

Since its introduction in 1917, the Cartier Tank has remained one of the most recognizable watch designs ever created. Inspired by the aerial view of military tanks used during World War I, its parallel brancards and balanced rectangular proportions became a defining element of Cartier design.

The Mini Allongée version offers a slimmer, elongated interpretation of the Tank silhouette. Its delicate proportions make it particularly elegant on the wrist, while maintaining the architectural purity that has made the Tank an enduring icon.

Case – Factory Diamond Set 18k Yellow Gold

The 18k yellow gold case measures 14 mm (excluding crown) x 28 mm, giving the watch its graceful elongated profile.

This example features a factory diamond-set case and crown, executed by Cartier using traditional sertissagetechniques. The diamonds enhance the refined character of the watch while remaining elegant and understated.

The case appears in excellent condition and was rhodium plated in the past, giving the gold a slightly lighter tone while preserving its original character.

Dial – Classic Cartier Elegance

The watch retains its original Cartier dial, beautifully preserved and displaying the timeless aesthetic associated with the Tank collection.

Elegant blue steel hands contrast perfectly with the dial, while the sapphire crystal remains spotless, ensuring excellent clarity and protection.

Movement – Cartier Calibre 28

Inside beats the Cartier calibre 28, a reliable quartz movement known for its precision and durability.

The movement is functioning perfectly and keeping excellent time, ensuring everyday usability alongside its collectible appeal.
