Black and White Driver Leather Strap
SKU: 304-BKW-18-ST
Black and white: motorsport's oldest contrast. That of panda dials, fabric helmets, smoky oil and petrol pits. The Driver was born from there — from the aesthetics of vintage racing, when a chronograph on a driver's wrist was a tool, not a style statement.
The leather is Italian full-grain calfskin: fine grain, compact fiber, a surface that doesn't surrender to wear but absorbs it and translates it into character. The edges are burned and sealed by hand, one by one — a process that protects the cut and, over time, builds a patina that each strap develops differently. The waxed polyester thread stitching follows the same logic as automotive saddlery: constant tension, uniform stitches, long-lasting durability.
The chromatic contrast is not decorative. It is structural. It works on a sports chronograph as well as on a dress watch, on a panda dial as well as on a skeletonized one. The Driver doesn't adapt — it remains itself and lets the watch find its own balance.

It softens to your wrist.
It starts firm and, week after week, takes the shape of your wrist. The surface grows warmer to the touch, the colour gains depth where the light hits it. No plastic on top: leather that ages honestly.

Frequently asked questions
Is the strap black and white as the name suggests?
The leather I work with here is black full-grain calfskin. The black-and-white contrast recalls the panda dials of motorsport, not the colour of the leather. Only the black version is available for purchase.
What sizes are available?
From 18 to 24 millimetres at the lug: 18x16, 19x16, 20x16, 21x18, 22x20, 24x20. Check your watch's lugs and choose the right one.
How does it change over time?
The edges are hand-burnished and sealed one by one. With use, each strap develops its own patina, depending on how you wear it, your wrist, and the climate.
Which buckles can I choose?
Steel, yellow gold-plated, rose gold-plated, or black PVD. I pair them all with the black strap; the choice depends on your watch's case.
Does it suit a sporty chronograph or only a dress watch?
The standard lug shape works on both. I fit it on chronographs, panda dials, and skeleton watches. The watch finds its own balance, the strap stays the same.
