Black Alligator Strap with Light Blue Edges
SKU: 403-BKLBL-20-ST
Louisiana alligator is not just a material—it's a statement. Tanned in Tuscany using the techniques of high-end Italian leather craftsmanship, this strap brings together two distant traditions in a single object: American raw material, European artisanal skill.
The black of the body is not uniform: each scale absorbs light differently, revealing depths that photos struggle to capture. The hand-painted light blue edges break the composure of the black without forcing a strong contrast—a precise, non-decorative choice. Those who notice it, understand it.
Each piece is unique by definition: the natural conformation of the leather ensures that no two straps are exactly alike. Small variations in tone compared to the images are not a defect—they are proof that no machine decided how it would turn out.

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 size is this strap?
At the lugs it is 20mm, tapering to 16mm at the buckle. The long side measures 115mm, the short side 75mm. The thickness is 2.5mm.
Which watches does it suit?
With its 20mm lug width, it fits Rolex, Breitling, TAG Heuer, Jaeger-LeCoultre, Patek Philippe, Vacheron Constantin and Breguet models that require this lug size.
Will the blue edges stay the same over time?
They are hand-painted, not printed. With wear, the colour evolves along with the strap, as happens with any hand-brushed finish.
Is every strap identical to the photo?
No. Alligator is genuine leather, and each scale has its own texture. Your strap will show slight tonal variations compared to the image: this is part of the material, not a flaw.
What buckle can I choose?
Four colours are available: steel, yellow gold, rose gold and black PVD. We recommend choosing based on the case metal of your watch.
