Black Alligator Strap with White Edges
SKU: 403-BKWH-20-ST
The Louisiana alligator needs no introduction. Every scale is a signature — unique, unrepeatable, never identical to the one on the strap next to it. This specimen is tanned and hand-finished in Tuscany, where the tradition of Italian leather goods meets the precision of haute horlogerie.
The deep black of the leather is interrupted by a white perimeter border: a sartorial detail that doesn't scream for attention, but is noticed. Anyone who sees it up close immediately understands that it is not a casual ornament — it is both a technical and aesthetic choice, typical of bespoke craftsmanship. The stark contrast between the dark body and the light thread gives the strap a rare visual presence, without sliding into excess.
Authentic alligator leather, unlike synthetic materials or treated bovine leathers, evolves over time: it settles on the wrist, gains luster with use, and develops a personal patina. It doesn't wear out — it defines itself.
A note on variations: each alligator leather is distinct in pattern and shade. The strap you receive may show slight differences from the images — this is your guarantee that you are not purchasing a mass-produced item.

Patina is the signature of time.
Alligator doesn't wear down: it matures. The first months on the wrist soften its flank, light darkens the ridges just slightly, and the colour deepens. We treat it with neutral oils, no varnish to smother the grain: what you take home isn't finished, it's only beginning.

Frequently asked questions
What are the measurements of this strap?
20mm at the lugs, 16mm at the keeper. Length 115mm case side and 75mm buckle side, thickness 2.5mm. Please take these measurements in hand before ordering.
Is the white edge trim hand-stitched?
Yes, this perimeter edge trim is hand-stitched. You can see it clearly up close: the light thread runs cleanly along the edge, without smudging.
How does alligator change over time?
It settles on the wrist and gains shine with use. It doesn't wear out, it defines itself. Each scale works in its own way, and after a few months the strap is no longer the one from the first day.
Will the scales be identical to the photo?
No, and it couldn't be otherwise. Each alligator hide has its own pattern, its own shade. Your piece will show slight differences from the image: it's real leather, not a print.
Which buckle should I choose with this black and white?
I've made available steel, plated yellow gold, plated rose gold, and black PVD. With this sharp contrast, I would go with steel or black PVD, to keep things understated. But the choice is yours.
