Strap Guide: Cartier Tank Must WSTA0041

The Cartier Tank Must WSTA0041 is a minimalist icon — a modern reinterpretation of the legendary Tank design, blending simplicity with elegance. With its brushed stainless steel case, clean dial layout, and refined shape, it’s the kind of watch that pairs perfectly with a quality leather strap. If you’re looking to replace or upgrade the strap, choosing the right fit and style is key to maintaining the Tank’s distinctive look.

This guide explains the exact sizing and most popular strap options for this reference.

Lug Width & Strap Fit

The Cartier WSTA0041 has a 19mm lug width, and like other Tank Must models, it uses standard spring bars (not QuickSwitch). The rectangular case requires a strap that’s slim and proportioned to match its straight lines. Generic straps may leave gaps or sit awkwardly — which is why we only offer curved-end straps made specifically for this model.

Our straps are built to follow the case contour for a smooth, integrated look.

Leather Straps for WSTA0041

Leather suits the Tank Must perfectly. We offer a wide range of custom leather straps tailored to this 19mm lug width — from traditional tones to bolder options.

• The black leather strap is a bestseller for its timeless look. It keeps the style sleek, formal, and versatile, echoing Cartier’s original design language.

• The green leather strap is a standout choice for those who want something more individual. It adds depth and personality without overpowering the minimalist dial, and is especially popular among owners looking to give the watch a fresh twist.

All straps are available for use with your original Cartier deployant clasp or a classic pin buckle.
