Cartier Tank Must! Haute Couture Edition in American Alligator Leather, available in six colors. The brand-new Tank Must watch was launched by Cartier in 2021. It Must be a TANK. Among all the classic Cartier Tank watches, if I had to choose one to wear daily, I would definitely pick the Tank Solo. However, this perspective may change with the latest TANK MUST of 2021. This year, the brand introduced the entirely new Tank Must series, which is regarded as a paragon of Cartier's elegant style thanks to its minimalist yet precise lines. The design innovates while maintaining the original design, with the lugs becoming more rounded and the dial proportions adjusted. Cartier has set a round cabochon crown with a convex gemstone, and it features an ultra-thin custom Swiss quartz movement with a finely detailed internal structure! The American alligator leather strap is exquisitely soft and fits perfectly! This Tank Must series watch also adopts the brand's signature square case! The small size measures 29.5 x 22 mm, and the medium size is 33 x 25 mm, with a thickness of 6 mm. The dial is silver-plated, equipped with sword-shaped blued steel hands, crystal glass, and a unique blue spinel set into the crown! Compared to previous models, the lines are more rounded and fluid. Additionally, the watch is equipped with a quick-release strap feature, greatly enhancing the comfort and convenience for everyday wear!
