The Tank WSTA0071, seen from the bench

The Tank Must Small is a quartz stainless steel watch with black dial, created by Louis Cartier in 1917 and inspired by Renault tanks from World War I. It features a rectangular case and vertical lugs that define geometric dress watch aesthetics. The Small model is part of the iconic Tank collection, known for its understated elegance and straight lines.

Frequently asked questions

Can I fit a standard strap on the Cartier Tank WSTA0071?

No. The bracelet is integrated into the case: Cartier's proprietary lugs don't accept off-the-shelf straps. I've seen too many attempts fail. The only proper path is building one bespoke, shaped by hand directly onto your watch.

How does the bespoke strap process work for the Tank?

I work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I measure the case, study the integrated lugs, and craft the strap piece by piece. No shortcuts: every detail is calibrated to your specific watch.

Which leather do you recommend for the Tank WSTA0071?

Mississippi Alligator with symmetrical scales. This watch breathes geometric elegance, clean lines, total understatement: a refined leather that wears beautifully and doesn't distract. If you prefer an alternative, supreme Swift in black or midnight blue carries the same restrained character.

How long does a properly made strap last?

It depends on use and care. An Alligator or Swift built with precision lasts 8–10 years of daily wear, handled thoughtfully. The leather ages in a controlled way, stitching holds firm, colours patina rather than fade. Someone who wears it with awareness watches it become more personal, not deteriorate.

Is the Tank really the watch Louis Cartier created in 1917?

Yes, born from Renault tanks during the Great War. It remains the manifesto of geometric elegance in watchmaking. This steel model preserves that legacy: pure lines, no compromise. For a watch like this, stylistic coherence is everything—the strap must breathe the same language.
