Tonneau Diamond 18k Rose Gold

Elegance is effortlessly expressed in this Cartier Tonneau reference WE400331, crafted in 18k rose gold and framed by a diamond-set bezel with a matching diamond-set crown.

The silvered dial complements the warmth of the rose gold case, featuring Cartier’s signature black Roman numerals, inner minute track and blued-steel hands. The elongated tonneau-shaped case gently tapers along the wrist, with prominent screws at each lug adding a distinctive architectural detail.

Powered by the Cartier caliber 8970 MC manual-wind movement, the watch is fitted with a narrow black Cartier alligator strap and secured by a Cartier 18k rose gold deployant clasp.

It is accompanied by a Cartier presentation box with a thoughtful two-tier design — the upper level dedicated to the watch, while the lower compartment provides additional sections for jewelry storage.
