Wonderful quality sturdy straps that are an excellent choice for chronographs or sporty watches. They are made of black calf leather with a carbon fibre grain, come in plain or rally styles and in 4 sizes (18-20-22-24mm) and with 2 keepers (one fixed and one floating). The straps themselves come with several colours of stitching (black, orange, red, white and yellow). Their length is approximately 85/115mm for the Rally-style and 100/120mm for the Plain-style ones that are also thicker and have a bigger steel buckle. I will include a pair of good quality spring bars with each strap. Feel free to contact me for whatever questions you might have.
