Cartier Tank Solo vs Tank Must

What is the difference between Cartier Tank Solo vs Tank Must?

Today we are going to talk about the difference between Cartier Tank Solo vs Tank Must. The main difference between the Cartier Tank Solo and Tank Must watches is in their watch case design and the materials used. Tank Solo XL is being replaced with Tank Must XL. Pretty much similar sizes.

The Cartier Tank Solo has a classic and timeless design, with a clean, simple and refined aesthetic. It features a stainless steel case, a silvered opaline dial with black Roman numerals, sword-shaped blued steel hands, and a sapphire crystal. It comes in a range of sizes, from small, large to XL.

The Cartier Tank Must, on the other hand, is a more modern and bold interpretation of the Tank watch, featuring a larger case and a thicker strap. It has a stainless steel case, a colored lacquered dial with black Roman numerals, sword-shaped hands with a luminescent coating, and a sapphire crystal.

The Extra-large model is powered by the caliber 1847 MC, Cartier’s entry-level in-house movement with 40 hours of power reserve. This model also has central seconds and a date aperture at 6 o’clock, courtesy of the movement, and features additional refined touches that include guilloche stamping on the dial and a beaded crown (the crown of the other two sizes is merely knurled). The small and large sizes are available as with a traditional quartz movement with a stated autonomy of 8 years – gem-set variants with brancards paved with brilliant-cut diamonds are also available (0.48 ct in the large model, 0.46 ct in the small model).

Finally, Tank Must have both easy switch strap and bracelet feature (and a better bracelet), which alone is a better feature for upgrade. But what about the rest when comparing on the straps? Which of them looks better? Thoughts?

Cartier Tank Must vs Tank Louis

When it comes to embodying the true essence of Cartier style, in my opinion, nothing quite compares to the Tank Louis Cartier. Whenever Cartier crosses my mind, it’s the Tank LC that immediately springs to attention. The esteemed George Cramer, a distinguished Cartier expert, once asserted in an article, “The Tank Louis Cartier reigns supreme among tanks.” Crafted solely from precious metals and adorned with a sapphire in its crown rather than the synthetic cabochon spinel seen in the Tank Must, it stands as the quintessential declaration of the Parisian brand’s elegance and sophistication.
