Red Alligator Strap Water Resistant
The red alligator makes no apologies. It's a declared, precise, uncompromising choice — for those who know the difference between a strap that's noticed and one that's worn with conviction.
The genuine alligator leather crafted by Casati Milano maintains its characteristics even when in contact with water: the tanning and finishing resist humidity without altering the leather's structure or the vibrancy of its color. The tone-on-tone stitching blends into the red, strengthening the strap's profile without visually breaking it. The thickness tapers precisely from the lugs to the clasp, ensuring a flat and natural fit on the wrist.
Each piece is unique: the natural pattern of the scales varies from hide to hide. Slight chromatic differences from the images are not a defect — they are the signature of authentic material.

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 sizes are available?
This red alligator is available in 20mm or 21mm at the lugs, always 16mm wide at that point. Case side 115mm, buckle side 75mm. Precise measurements, not approximate.
Can I get it wet without any issues?
Yes. The tanning and finishing of this alligator resist moisture. The colour does not change, nor does the structure of the leather. That said, I wouldn't leave it soaking for hours, but a bit of rain won't ruin the strap.
Does it look good on a Rolex or a Breitling?
With 20mm or 21mm at the lugs, it fits many models, including Rolex and Breitling. I'd recommend checking the exact lug width of your watch before choosing between the two.
Is every piece identical to the others?
No, and I'm happy to say this clearly. The scale pattern varies from hide to hide: it's genuine alligator, not a print. Slight tone differences compared to the photo are normal and are part of the real material.
Can I have traditional spring bars instead of the quick release?
Yes, this can be done on request. Same price, about a week's wait. Just confirm the size for me, 20mm or 21mm, and I'll proceed.
