Throwback Thursday; Cartier Tank à Guichets

The history of Cartier is filled with many incredible watches, often in unique shapes. Over the years, many have become icons of 'La Maison' and gathered quite a few fans along the way. Others remain somewhat of a mystery, as they are so rare that they hardly ever come up for sale, and are often not more than a footnote in most books. This is also the case with the Tank à Guichets, with its novel way of indicating the time.
