An absolute classic: the Cartier Tank is one of those watches that needs no introduction.

Launched in the late 1970s, the Must line brought the iconic Tank design to a wider audience without compromising the elegance that made Cartier an undisputed benchmark. Among the versions produced, few are as exclusive as this rare "Turtle Shell" Brown Wood Dial, with a dial inspired by the natural tones and textures of wood, creating a beautiful interplay of light and lending the watch a unique character.

This particular example impresses with its condition: it is simply impeccable, with its Plaqué G20M (vermeil) case—Cartier's traditional gold-over-silver coating used at the time—exceptionally well preserved. The classic crown with a black cabochon, elegant gold sword-shaped hands, and manual-winding movement complete an extremely refined piece.

Another distinctive feature is that this is the GM (Grand Modèle), rather than the more common PM (Petit Modèle)—a detail that surprises even many collectors and ensures an even greater presence on the wrist without losing the Tank's characteristic elegance.

To complete the set, it comes with its original Cartier box and original Cartier-signed strap, a combination that is increasingly difficult to find in such well-preserved condition.

A rare, sophisticated Tank full of character, perfect for anyone seeking a much less common alternative to traditional white or black dials and who values originality in every detail.
