I believe that Cartier Tank is not a secret for a watch lover. This model is widespread, still available in the Cartier collections (http://www.en.cartier.com/collections/watches/mens-watches/tank.html) and the offer on the pre-owned market is generous.
During my searches, I have encountered some nice models but one, in particular, made a deep impression – The Cartier Tank Basculante.
Release year – 1933 (some say in 1932, but on the Cartier website is stated 1933 as the official release), reason – special clientele who requires a watch with protected bezel and dial, the main competition was Reverso.
Unfortunately, this watch is not in the current collection, but there are some very lovely pieces on the pre-owned market.
Here is a nice video from LuxWatch.com with a Cartier Tank Basculante WA203351
