Cartier Tank Solo SM Steel/Steel Quartz – Model 3170. Case size is 24x31mm. Suits men and women. The watch is in very good condition. The case and bracelet have light scratches throughout from gentle use. There are no visible marks on the crystal. All functioning as expected. Comes with the original box, a Cartier service/travel pouch, as well as a grained black leather strap and double-deployment steel clasp. The interior of the original box is in poor condition with the white leather-like material peeling in places, as to be expected from its age. Don’t hesitate if you have any questions. Open to reasonable offers.
