Tapered sizes:
Tapered size refers to a gradual reduction in watch strap width from one end to the other. In the context of watch straps, a tapered design typically features a wider width near the lug attachment point of the watch and gradually narrows towards the buckle or clasp end. This tapered shape not only enhances the aesthetic appeal of the strap but also offers a comfortable fit, ensuring it conforms smoothly to the wrist. Tapered straps are often favored for their stylish look and ergonomic design, providing a sleek and refined appearance when paired with various timepieces.

Please Note:
The wrist size mentioned refers to the circumference of your wrist at the location where you typically wear your watch.
The length guide provided is approximate and applies to the straps depicted in the images. Variations in fit may arise due to variances in wrist shapes, buckle or clasp types, and differences in watch case sizes or shapes, which cannot be entirely accounted for.
Additionally, individual differences in hand size and structure may further influence fit.

Every bison leather watch strap carries a history written by wind, sun, and time. The Prairie Brown Bison Leather Watch Strap is no exception. Made from genuine North American bison leather — a material encountered several times less often than traditional calf leather — its rich brown tone and bold natural grain reflect a life shaped in the open plains. No two straps will ever look the same.
Bison leather has a long, practical history. For centuries, it was used by Indigenous peoples of North America for clothing, shelters, and essential equipment — a true working material chosen for strength and reliability. That same character defines this strap today.
Handcrafted in Finland, the Prairie Brown strap balances rugged durability with refined craftsmanship. At around 3.5 mm thick, it feels solid yet comfortable, gradually softening and adapting to your wrist with wear. The warm brown color adds depth and character, pairing equally well with casual watches and more formal timepieces.
We don’t rush production or cut corners on materials. Every strap is made with care, from sourcing the leather to the final hand-finishing, as a finished accessory for watches you truly value.
We also give you the freedom to make your strap your own. Choose the lining material, stitching color, and buckle finish. Other customization options may be possible — just contact us by email to discuss the details.
You won’t find this strap anywhere else. We control every step of the process, ensuring that each piece remains an exclusive FinWatchStraps creation.
