Our full grain and vegetable tanned Italian leather straps are made from a single layer of leather making it strong, durable and immune to wear and tear. Tanned using the oldest plant-based tanning methods, giving it a rustic look, and a warm and silky touch. The blue leather strap with cream row-stitching has a thickness of 3.2mm and works particularly well with dark blue, salmon, champagne or cream-colored dials.
