In the same decade, Cartier launched Tank models that are more unusual but are still refined and easy to wear. Two of these models – the Cartier Tank Obus and Cartier Tank à Guichet, would later be relaunched for a short period.
The Cartier Tank Obus (right) first appeared in 1923. Characterized by a square case, bullet lugs, and a busier dial with both Roman and Arabic numerals – it’s definitely not your average Tank. The last Tank Obus was released in 1998 for the Collection Privée Cartier Paris series.
In 1928, Cartier launched its first jumping hour wristwatch – the Tank à Guichet. Instead of an analog display, it had two windows that show the hour and the minutes, much like a mechanical digital watch. The Tank à Guichet was revived in 1997 to commemorate Cartier’s 150th anniversary, and were last produced in 2005.
