*Unpolished* 1970s Cartier Tank Automatique 18K YG (Ref. 17011) "Jumbo"

The Cartier Tank has become one of the most iconic watch designs of all time, and other than some more eclectic references produced has remained relatively the same over its long run of production. The very first Cartier Tank, the Tank Normale, was originally designed in 1917 and became commercially available in 1919, and its design was inspired by the Renault FT-17 tank used by the French Military in the First World War. 

The Cartier Tank is the perfect example of excellent design transcending generations. The Tank moved through the early 20th century only to become more relevant during the mid-century design era, and is once again seeing a massive resurgence amongst the watch-collecting community today.

The Tank Automatique ref. 17011 "Jumbo" is a true anomaly produced by Cartier that has become exceedingly collectible throughout the years. Only produced for a short period of time in the 1970s, these larger Tank wristwatches made a lasting impression. Interestingly, the original Tank Automatique "Jumbo" was produced in two sizes, the "Jumbo" ref. 17011 and the larger "Jumbo XL" ref. 17002. The movement used is a simple yet reliable ETA-based time-only movement, and the case back was manufactured to fit around the movement in a unique bubble design so as to eliminate any excess material and maintain the Tank's minimalist personality.

The remarkable 18K yellow gold case is believed to remain unpolished as the original factory geometry and dimensions appear to remain untouched and unaltered, with all of the hallmarks and factory markings presented in super crisp and original condition. The case retains its original blue sapphire cabochon crown. The back of the case showcases the "bubble" that holds the movement and features a light rosy patina that is formed on yellow gold cases that have not been polished. The watch comes supplied on a custom Jean Rousseau matte black alligator leather strap that will fit a 6 3/4-inch wrist and features an 18K yellow and rose gold Cartier deployant buckle. 


The original white Roman numeral "Swiss" dial is in truly excellent condition, the dial features some minor surface spidering that is commonly seen in Cartier dials of this era, though no actual damage, age, or chipping is present. The original blued hands are in flawless condition.


None. The watch is keeping time perfectly, backed by a 1-year warranty on accurate timekeeping.
