Colour: mixed with main color black
Material: woven nylon, mixed colours so it looks like Harris tweed.
Edges and holes are laser-sealed so all should be smooth. Hardware is kept in place by stitching. End points of the stitches can be melted and pressed flat with a small flame.
The buckle is attached with a push pin, so you can replace it with a buckle of your watch-brand.
Buckle and loops are 316L steel, brushed finish.
