Which leather strap for a Cartier Tank?
The ultimate rectangular watch, the Tank is inseparable from its leather strap. First, you need its exact size.

One family, several widths
Tank Louis Cartier, Must, Française, Américaine: lug widths run from 16 mm on small models to 23 mm on the extra-large Must. The Tank Américaine, with curved lugs, needs a bespoke strap. Find every model on our Cartier Tank strap page.
Alligator, the historic choice
The Tank is traditionally worn on alligator with large square scales. Semi-matte is the most elegant; glossy suits evening wear.
Lizard, for small models
Its fine, regular scales stay legible on a 16 or 17 mm strap, where alligator scales would look too large.
Colours
Burgundy, bottle green and navy are Tank classics. On yellow gold, try cognac; on steel, grey or black. Bright ostrich colours give a more modern reading.
The deployant clasp
If your Tank has an original deployant clasp, you can reuse it: enter its inside width in the bespoke configurator.
