It's a cool grey calf leather with a natural grain on the outside and a contrasting tan lining on the inside, giving it a two-tone look. The edge stitching is colour-matched to the exterior, so the overall finish feels considered rather than generic.

Yes, that's actually part of the appeal. Calf leather ages naturally with wear, gradually softening and developing a character that feels personal to you.

It uses a classic silver buckle fastening, visible in the product images. It's straightforward to put on and gives a secure, adjustable fit.

The strap is designed as one size fits all, with multiple adjustment holes along the strap to accommodate different wrist sizes. You can see the adjustment holes clearly in the product images.

The strap is made from calf leather on the exterior with a contrasting interior lining. The attributes confirm it's a genuine leather construction, and the grain texture is visible in the close-up product imagery.
