This Cartier caliber 690 quartz movement was found in Tank de Cartier model. The watch itself is ultra slim, measuring at about 5.6mm thick. This movement is also used in other Tank models, such as the Tank Solo Large.
You will find many sites incorrectly listing the caliber 690 as having 7 jewels, but since most of the other sites out there don’t actually bother to open each watch, they failed to see that the 690 actually has 8 jewels.
This movement is also the same as the Ebel caliber 690.
