To mark the 100th anniversary of its most iconic timepiece, Cartier is introducing a brand new model. Here's what you should know about how the Tank Watch came to be.

11. Andy Warhol wore one, but only for show.
"I really don’t wear it to tell the time," the pop artist said in an interview.
12. A new model joined the lineup on September 1.
Cartier just introduced two limited-edition collections of the Tank Cintrée Skeleton watch (left) to celebrate the Tank's 100th anniversary. It joins the Tank Française, which was first produced in 1996, the Tank Ame?ricaine, first designed in 1987, and the Tank Louis Cartier.
