Over the years, the Tank Basculante has become an appreciated part of Cartier’s watchmaking history. Its unusual case construction, distinctive appearance and relatively uncommon presence on the vintage market make it particularly interesting to collectors. What began as a practical approach to protecting a watch evolved into one of Cartier’s more distinctive interpretations of the classic Tank design.

The example presented here is from the late 1990s and in excellent condition. It was already remarkably well preserved when we acquired it, despite not having received a service for 24 years. More recently, the watch returned from Cartier's official service centre, where it underwent a comprehensive service. As part of this work, the necessary components of the pivoting mechanism were replaced with the correct parts, restoring its proper operation. Following this service, the watch presents in virtually new condition, with its original case surfaces and distinctive construction exceptionally well conditioned.

The watch is fitted with a navy blue Cartier alligator leather strap, secured by its original Cartier C-shaped folding buckle. Its beautiful cream-coloured dial features Cartier’s characteristic guilloché decoration, complemented by elegantly painted Roman numerals. Above the vertically positioned winding crown sits the natural blue sapphire cabochon, an unmistakable detail of Cartier watch design, which remains completely free from visible damage.

A small detail worth knowing: With the pivoting arms extended and positioned upright, the Cartier Tank Basculante can also be used as a small desk clock, adding another practical dimension to its ingenious case construction.

The Cartier Tank Basculante is a fine example of Cartier’s ability to combine distinctive design with mechanical ingenuity. As mentioned above, this particular example has recently undergone a complete service at Cartier’s official service centre, including the replacement of the necessary components within the pivoting mechanism, replacement of crucial movement parts and replacement of the sapphire crystal. The watch will be delivered with a two-year Cartier/WatchWorks mechanical warranty, accompanied by the very first service record dating back 24 years, the original Cartier service folder and the original Cartier velvet service pouch.
