The Heritage

The Tank was introduced by Cartier in 1917 as a watch with geometric lines inspired by military vehicles. The reference W5310047 is equipped with the Cartier Calibre 049 movement, providing hour, minute, second and date indications. The movement offers essential functions in a format that maintains the classic proportions of the original model.
Made to Measure

The strap for this watch is made to measure

On the Cartier Tank the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a standard strap be fitted to the Cartier Tank W5310047?

No, the W5310047 features a proprietary lug attachment that does not accommodate standard straight-bar straps. However, a bespoke strap crafted by <a href="/pages/casati-booking">Casati Milano</a> fits perfectly, replicating the exact dimensions of your case. The atelier measures your watch and builds a strap designed exclusively for this model.

How is the bespoke strap constructed for the Tank W5310047?

The artisan at Casati Milano measures the lugs and proprietary attachment of your case, then constructs the strap model-by-model. Every element—the strap body, the passants, the buckle or deployant—is calibrated to your watch's actual dimensions. The result is a strap that adheres seamlessly and appears integral to the case.

Which leather material suits the Cartier Tank W5310047 best?

The Tank demands leathers that respect its dress and geometric character. Calf leather in ochre tones with evolving patina, Nile crocodile with regular scales, or fine alligator with subtle grain are ideal choices. Avoid high-gloss mirror-polished leathers: the Tank needs none, and they risk compromising the aesthetic balance Louis Cartier conceived in 1917.

How long does a strap made by Casati Milano last?

A bespoke strap crafted with selected leathers and quality finishing can endure ten, fifteen years or longer, depending on frequency of wear and maintenance. Leather ages, acquires patina and character; this is not a flaw but proof of its authenticity and solid construction.

Why is the 2012 Tank W5310047 still a relevant choice today?

The Cartier calibre 049 is a reliable movement, free of unnecessary complications, keeping hours, minutes, seconds and date. Steel and yellow gold age nobly. The 30-millimetre case, slender and geometric, remains intelligent as it was in 1917 because it does not follow trends; it embodies a durable aesthetic principle. It is a watch that teaches rather than dictates fashion.
