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 character shaped by nature and time. The Dark Grey Bison Leather Watch Strap expresses this in a restrained, understated way. Made from genuine North American bison leather — a material encountered significantly less often than traditional calf leather — it features a deep dark grey tone with a pronounced, natural grain. Each strap is unique, marked by the natural structure and texture of the hide.
Bison leather has a long history as a practical, hard-wearing material. For centuries it was used by Indigenous peoples of North America for clothing, shelters, and essential equipment, valued for its strength and reliability. That same durability defines this strap today.
Handcrafted in Finland, the Dark Grey strap balances robustness with careful workmanship. At approximately 3.5 mm thick, it feels solid on the wrist while remaining flexible and comfortable. With regular wear, the leather softens and adapts to the wrist, while maintaining its shape and resistance to stretching. The dark grey color pairs especially well with steel cases, tool watches, and modern or minimalist designs.
We do not rush production or compromise on materials. Each strap is cut, assembled, stitched, and finished by hand, with quality control at every stage. It is made as a long-term accessory — not a disposable item, but something meant to age alongside your watch.
Customization is available. You can choose the lining material, stitching color, and buckle finish. Additional options may be possible; feel free to contact us by email to discuss your preferences.
This strap is exclusive to FinWatchStraps. By controlling every step of the process, from leather sourcing to final finishing, we ensure consistency, durability, and individuality in every piece.
