The Cartier model that you see here, the Tank Louis, is perhaps the most classic model of Cartier. Actually unchanged for years. Of course, the timepieces have changed over the years and since the Must de Cartier models were offered, Cartier has a more affordable model in the collection. This Must de Cartier has a silver case in the base with a golden layer around it. The timepiece of this model is a Quartz timepiece, where there are also models with a mechanical (handwind) timepiece.
The watch has of course been serviced. The size of this model is 20 mm wide and about 18 mm high, a real elegant size. Almost all Cartier models have the characteristic Roman index and sapphire crown. A beautiful detail.
