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.

This watch strap is made from traditional Tuscan vegetable-tanned leather produced by the Badalassi Carlo tannery in Italy. The leather is enriched with natural oils and waxes and softened through a milling process, giving it a comfortable feel from the first wear and a pronounced pull-up effect.
When the strap bends, the tone lightens at the fold as the oils shift inside the hide. This creates depth, natural variation, and a lively character. Thanks to the high oil content, the strap feels soft immediately, offers a secure grip on the wrist, and does not require a break-in period. Small surface scratches can often be reduced or hidden with light rubbing, as the waxes warm up and blend back into the leather.
Over time, the leather develops a rich patina. The matte surface becomes smoother and slightly glossy in areas of natural friction, and the color gradually deepens with wear. The natural Tuscan aroma — a mix of bark, oils, and waxes — also remains noticeable.
Each strap is handmade in Finland in small batches. Cutting, shaping, stitching, and finishing are completed manually. Natural differences in grain, tone, and pull-up behavior make every strap unique.
This strap works well with casual and vintage-style watches. If you’d like help choosing the right tone or texture for your watch, you can explore our guide:
