Black Alligator Strap with Light Red Edging
SKU: 403-BKRE-20-ST
The hand-painted edge is the last thing you notice — and the first thing you remember. Against a compact black background, the light red edging traces a precise, millimeter-perfect perimeter, almost like a signature. It's not a decorative detail: it's a statement of character.
The leather is Louisiana alligator, tanned in Tuscany according to a tradition that allows no shortcuts. The manufacturing process begins with the selection of each individual hide — every piece has a different conformation, and that difference is evident in the finished strap. The surface is that of genuine alligator: defined scales, natural relief, a texture that changes slightly from one piece to another.
The light red edging is applied by hand, in layers, after stitching. It's not an industrial finish: it requires time, a keen eye, and a steady hand. The result is a line of color that complements the watch case without overpowering it.
Each strap is handmade in Italy. Color variations between individual pieces are inevitable — and are part of the product.

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
Does the light red edge trim hold up over time, or does it tend to flake with use?
The edge paint is applied by hand in multiple layers onto already finished leather, which ensures good adhesion over the long term. As with any artisanal pigment-based finish, it may show slight wear in the areas of more frequent contact — particularly near the lugs — after years of intensive use. Periodic maintenance with products specific to fine leathers helps preserve its integrity.
Is this 20mm strap compatible with cases that require a 16mm buckle?
Yes. The tapered profile goes from 20mm at the lugs to 16mm at the buckle keeper, a classic proportion for watches from 38 to 42mm in diameter. The 20/16mm size covers most standard configurations, including many Rolex, IWC and Jaeger-LeCoultre models with a 20mm lug width.
What distinguishes this strap from a standard black-dyed alligator strap?
The main difference is the light red edge, hand-painted, which introduces a calibrated splash of colour against an otherwise rigorous background. This is not a 'sporty' or eccentric strap: the red is restrained, used as a perimeter rather than as the protagonist. The result works well on steel or bicolour cases where you are looking for a discreet point of visual tension.
Is the 2.5mm thickness compatible with cases that have narrow lugs or with deployant clasps?
A thickness of 2.5mm is amongst the slimmest for genuine alligator — and this makes it versatile even with low-profile cases or lugs with limited clearance. With deployant clasps, compatibility needs to be checked case by case, as the strap's thickness affects the overall height of the clasp on the wrist.
