Black Saffiano Rubber Strap
SKU: 901-SAF-BLK-20-ST
Under your fingers, you first feel the texture—that fine, regular saffiano grid that leaves no doubt about its origin. Then you notice the reverse: thick, compact natural rubber, silent on the wrist.
The Rubber Black Saffiano is born from the encounter of two materials that rarely interact. Saffiano leather, with its cross-hatch surface, brings visual character and resistance to surface wear. Natural rubber—caoutchouc, not silicone—does the invisible work: it absorbs shocks, breathes through integrated ventilation grooves, does not react to UV rays or contact with chemicals. And it is latex-free, a detail that matters more than you might think in long-term daily wear.
Black here is not a simple choice: it is the compact black of natural caoutchouc, which does not fade, and the black of saffiano that maintains its matte luster over time. The stainless steel quick-release allows for quick strap changes without tools—useful when you have multiple watches, essential when time matters.
A strap designed for daily use without compromising on character.

Frequently asked questions
What sizes are available?
I have two sizes in the catalogue: 20mm x 18mm and 22mm x 20mm. Check the lug width of your watch and choose accordingly.
Is the quick-release used without tools?
Yes. It's made of stainless steel, integrated into the lugs. Press the lever and the strap releases, no screwdriver or toothpick needed.
What is inside, underneath the leather?
Natural rubber, caoutchouc. It's not silicone. You can feel it on the underside: dense, thick, quiet on the wrist.
Is it suitable for people with allergies?
The natural rubber I use here does not contain latex. A detail that matters, if you wear it every day.
Is the colour always identical from one piece to another?
There may be slight colour variations from one strap to another. This is the nature of the material, not a defect.
