Originally designed in 1917 by Louis Cartier, the Tank watch drew inspiration from the bold lines of the Renault tanks used on the Western Front during World War I. Its clean, rectangular form—with vertical sidebars known as brancards—echoed the silhouette of those early armored vehicles. Over the past century, the Cartier Tank has become an enduring icon of design, worn by cultural figures and celebrities long before the rise of modern brand ambassadors.
Among the most recognizable evolutions of the Tank line was the Tank Solo, which reigned as the go-to entry-level model for decades until its discontinuation in 2021, when it was succeeded by the Tank SolarBeat. While faithful to the Tank’s heritage, the Solo brought subtle refinements that set it apart. This stainless steel reference retains signature design elements—like the cabochon-set crown, solid caseback, and brancard-style case sides—but introduces a more contemporary feel with its slightly rounded case flanks and flat-topped profile, creating a bolder presence on the wrist.
The dial blends classic Cartier aesthetics—black Roman numerals, thermally blued sword hands, and a central minute track—with an unexpected twist: a rare and refined pink dial that adds a touch of playfulness while maintaining the sophistication the Tank is known for.
This particular Tank Solo reference 3170 is in overall outstanding condition. The case remains unpolished, preserving its original lines and definition. The uncommon pink dial is clean and free of blemishes. The original blued steel hands and blue sapphire cabochon crown are in excellent condition. Powering the watch is Cartier’s reliable quartz caliber 157, which was just serviced in May 2025 and fitted with a new battery. The watch also comes with a brand new Cartier red alligator strap fitted with its original Cartier steel deployant buckle. The watch is offered with its original box (no papers).
