Strap for Cartier Tank Must (2021 - today) - The Grana Royal Blue

Modern Parisian

Grana Leather - Deep Blue

Blue brings out a wonderfully contemporary side of the Tank Must. The rich Royal Blue connects subtly with Cartier's signature blued hands and cabochon, while creating a cooler, more modern relationship with the steel case. The natural Grana texture keeps the colour sophisticated rather than overly polished, giving the watch a relaxed elegance that feels particularly suited to the modern Tank. It is distinctive without becoming loud - a small change that completely shifts how the watch feels on the wrist. At only 2.3 mm, the strap remains slim, soft, and comfortable, respecting the Tank's refined proportions. A stylish alternative to black for those who want their Cartier to feel a little less expected.
