The 'Unknown' Cartier Tank: The Louis Cartier Jumbo

Next to the classic men's model, Cartier released a small run of the Tank Louis Cartier XL version in 2006, a watch featuring 30 x 39.2 mm case dimensions The Jumbo is also the only Tank Louis Cartier equipped with an automatic movement, Caliber 170 The difference between the Jumbo and other Louis Cartier Tank models becomes immediately clear when the watch is turned over.

While the Tank Louis Cartier is known to have a flat case back, the Jumbo has a round thickening that gives away the fact that there is an automatic caliber inside this case with more height than the hand-wound calibers the line usually offers Despite the small bubble on the back, the case of the Jumbo is unmistakably Tank Louis Cartier with its two screws on each case side holding the back tight and the plain, screwless back with the usual engravings and gold stamps At SIHH 2018, Cartier presented a good-looking renewed version of the Tank Louis Cartier in yet another case size just a little larger than the classic version at 255 x 337, but still a lot smaller than the Jumbo.

As Cartier only made a small run of these Jumbo Tanks back in the 1970s, which over the last few years has suddenly gained interest among Cartier fanatics, the pre-owned price of the yellow and white gold Jumbo models has now surpassed the price of a classic Tank Louis Cartier in platinum with hand-wound caliber. .
