Alligator

IT: Alligatore - pelle di alligatore

Definition

Alligator and crocodile are not the same thing, even though shops often treat them as synonyms. Alligator leather — Alligator mississippiensis, farmed mainly in Louisiana — has symmetrical scales and a regular texture that makes it immediately recognisable. It is the material I use when a client wants the utmost distinction without ostentation. The fibrous structure of alligator is more compact than that of niloticus crocodile: it withstands moisture better, bends without giving way, and ages with a sheen that intensifies rather than dulling. A handmade alligator strap, with a good calfskin lining and saddle stitching, can last twenty years with minimal care. Tanning is the variable that separates a mediocre alligator from an extraordinary one. I only work with CITES-certified hides, vegetable-tanned when possible — the result is a leather that responds to use instead of wearing out. The colour penetrates deeply, it does not stay on the surface as it does in industrial alligators. As for pairing: on a Patek Philippe Nautilus I prefer midnight blue alligator at 20mm with contrast stitching. On a Royal Oak, glossy black works well. On a Datejust, cognac with a steel buckle. These are pairings I have made hundreds of times — not theoretical combinations.

Frequently asked questions

What is the difference between alligator and crocodile for a strap?

Alligator (Alligator mississippiensis) has symmetrical, regular scales, with a more compact texture. Niloticus crocodile has irregular scales with a typical asymmetrical pattern. The fibrous structure of alligator withstands moisture better and bends more softly. For everyday use I prefer alligator — I reserve crocodile for ceremonial watches.

How do you care for an alligator leather strap?

Not much, and with the right products. Once a month, a light application of colourless cream for exotic leathers — never products for bovine leather, as they have a different pH. Avoid direct water and prolonged sweat: alligator holds up well, but vegetable tanning reacts to constant moisture. If it gets wet, let it air dry away from heat sources.

What sizes are available for Milano Straps alligator straps?

I make alligator straps from 18mm to 22mm lug width, with standard or bespoke taper. The standard length is 120/75mm, but I adapt it to the wrist on request. For Casati Milano bespoke pieces, any size is possible — just tell me the watch and the wrist.
