Few watches have the same level of timeless elegance as the Cartier Tank. Born from the imagination of Louis Cartier in 1917, the design was inspired by the Renault tanks used during World War I. The bold, geometric case of this watch has turned it into an Art Deco icon and revolutionized watchmaking by breaking away from traditional round cases.
Over the years, Cartier has introduced various iterations of this legendary timepiece, including the Tank Solo and the Tank Must. Both models pay homage to the original while offering their own unique take on the classic design. If you’re deciding between the Tank Solo vs Tank Must, here’s what sets them apart.
Cartier Tank Solo Review
Introduced in 2004, the Tank Solo was designed as an accessible entry point into the world of Cartier. Its case, available in small, large, and extra-large sizes, stays true to the classic Tank silhouette with its flat, sharp-edged brancards that mirror the clean lines of the Tank Louis Cartier. The domed blue synthetic spinel cabochon crown adds a touch of refinement, while its silvered opaline dial, black Roman numerals, and blued-steel sword-shaped hands are known hallmarks of Cartier.
The Tank Solo was offered in a steel case with matching bracelet or leather strap, as well as steel and yellow gold or steel and rose gold variations. Inside, the watch is powered by a quartz movement for the small and large models, while the extra-large version is powered by Cartier’s automatic caliber 1847 MC.
Although the Tank Solo has been discontinued, it remains a highly sought-after piece in the pre-owned market. Its close resemblance to the iconic Tank Louis Cartier make it a cherished option for limited-edition collectors and first-time buyers alike.
Cartier Tank Must Review
The Cartier Tank Solo was discontinued in 2019 and replaced by the Tank Must in 2021. While it retains the essence of the original, the Tank Must brings subtle refinements that set it apart. The Tank Must’s case appears slightly thinner and more elongated, with brancards featuring rounded edges for a softer look. Another notable change is the more pointed blue cabochon that adds a modern touch to the overall design.
The Tank Must also embraces a bolder approach to dial variations. Alongside the classic white dial with black Roman numerals, Cartier introduced a striking monochromatic black version and a diamond-set bezel for those who prefer a touch of luxury. Just like the Tank Solo, it houses a quartz movement in the small and large models, while the extra-large model runs on the automatic caliber 1847 MC. Additionally, Cartier introduced the innovative SolarBeat movement in select Tank Must models, offering a sustainable, solar-powered option to maintain the watch’s timeless aesthetic.
Cartier Tank Solo vs Must: Which One Should You Choose?
When comparing the Cartier Tank Must vs. Solo, the decision ultimately comes down to whether you prefer the Tank Solo’s sharper, more traditional lines or the Tank Must’s modern updates.
If you love tradition and want a watch that closely resembles the original Tank or the Tank Louis Cartier, the Tank Solo is a fantastic option, but only if you can find one in the pre-owned market. On the other hand, if you’re drawn to a more updated or more sustainable version, the Tank Must is the perfect fit. Both models embody Cartier’s signature elegance and craftsmanship, ensuring that whichever one you choose, you’ll be wearing a true Art Deco icon on your wrist.
