The Mast Tank is based on the "Tank Series" inspired by French tanks.
The square dial imitates the caterpillar of a tank, and its sophisticated design is said to have attracted attention.
On the other hand, the price range unique to high-end brands was one of the barriers, and there was also the background that only a few fans were able to own it.
I want it, but I can't afford it... While potential fans continue to burn their hearts, the Must Tank was born.
The beautiful design of the "Tank Series" is kept at an affordable price.
As a result, the must tank became a frenzy at the time, and carved its name into Cartier's history.
And even now that production has ended, the must tank boasts a strong popularity as an antique watch.
