This lot has no reserve
The following two lots are part of a limited edition of the Tank Basculante made in 2000 to celebrate the new millennium and a re-edition of the original model launched in 1932.
The main purpose of this ingenious system, allowing the complete 360 degree rotation of the case around the horizontal axis, was to protect the crystal and consequently the dial during sporting activities.
The model is illustrated and described in Cartier - The Tank Watch by Franco Cologni, pp. 97-100 & 214-215.
