Black Alligator Grain Strap for Cartier Tank Solo
Italian calf leather pressed with a square-scale alligator grain in black, handmade to fit the Cartier Tank Solo and Cartier's double fold clasp. It's the classic dress-watch look the Tank was made for.
Made for the double fold clasp. Both halves are the same length, 105mm each (115mm on the 23mm), with a 2mm taper towards the clasp (5mm on the 23mm). It uses your original Cartier clasp, so no clasp or buckle is included.
Available in 16mm, 17.5mm, 18mm, 20mm and 23mm. Measure the gap between your lugs to find yours.
Not a genuine Cartier strap. It's an aftermarket strap made to fit. Cartier® is a registered trademark of Cartier International AG, and this strap isn't made, approved or endorsed by them.

What the measurements mean
- Width: fits between your watch's lugs, so match it to your lug width (a on the diagram).
- Length: both pieces added together. Both halves are the same length, which is how Cartier's double fold clasp needs them (d).
- Clasp width: the strap narrows towards the clasp, so this is its width at that end.
- Clasp: made for your original Cartier double fold clasp, which isn't included.
