Red Ostrich Leg Strap for a Cartier Tank
Share
Sourcing a strap for a Cartier Tank through Cartier is slow and expensive, and the case is small enough that a generic band rarely sits right. This one was built in red ostrich leg for an order from New Jersey — a bold color on a classic dress watch — cut short at 65/105mm with a narrow 14mm gold buckle to keep the proportions true to the Tank.

Why these choices
Ostrich leg leather comes from the bird's lower leg, with a natural scaled grain that runs in tight rows. It is a crisp, almost reptilian texture, quite different from the bumpy round-skin ostrich most people picture — closer in look to a fine lizard or snake than to classic ostrich. That structured grain gives a small dress watch some character without adding bulk.
Red is the bold move here. On a Cartier Tank, a red strap turns a restrained dress watch into something with a bit of personality, and ostrich leg carries strong color particularly well because the scales catch the light. It is the sort of choice that works precisely because the watch underneath is so classic.
The Tank is a small, rectangular case, so the strap was cut short at 65/105mm and tapered to a narrow 14mm gold buckle. Gold hardware matches the warm tone of most Tank cases, and keeping the buckle narrow stops the strap from looking oversized against the slim lugs. We fit regular spring bars sized to the case.
This was one of two straps the customer ordered for the same Tank, swapping the watch's look without buying a second watch — the kind of thing a made-to-order strap makes easy and a factory replacement does not.

★★★★★
“This is a great strap that fits perfectly. As a bonus this was much easier than working with Cartier for a strap. This was my 3rd strap from VGreen because these are unique and well made.”

FAQ
Will a red ostrich leg strap for the Cartier Tank fit my watch?
Yes. We build to order for the specific Tank reference, so send your model or lug width and wrist size and we cut the length, taper, and buckle to match.
Is ostrich leg the same as regular ostrich?
No. Ostrich leg has a scaled, rows-of-grain texture from the bird's leg, while round-skin ostrich has the familiar raised quill bumps. They are different leathers with a very different look.
