Fit & sizing notes for the Tank Must (Large)
- What to buy: straps made for the Tank Must (Large), or an adapter kit for this exact model. A normal-width strap won't attach on its own. Our integrated & smartwatch strap guide explains the options.
- Adapters stick out past the case, so the watch wears longer; check the adapter's output width before buying straps for it.

Cartier Tank Must (Large) — strap questions
What strap size does the Tank Must (Large) take?
The Cartier Tank Must (Large) doesn't use standard spring-bar lugs — it has an integrated/proprietary fitting, so you need Tank Must (Large)-specific straps (or, where one exists, an adapter kit) rather than a normal strap.
Can I put a normal NATO or leather strap on it?
Not directly. A standard strap won't attach on its own. Where a model-specific adapter exists, fit that first and then a normal strap of the adapter's width.
Where can I buy straps that fit the Tank Must (Large)?
Search for straps and adapters made specifically for the Cartier Tank Must (Large); generic sizes won't clip in without one.
