Handmade Straps
Minimalist Bio Rubber Apple Watch Strap
€45,00
Rubber, but not as you know it. Bio rubber is a material made from renewable sources, performs like technical rubber, and disappears without a trace. For those who wear an Apple Watch and don't want to compromise on their wrist or what they wear.
The lines are clean, almost essential. No visible stitching, no decorative details: the strap works by subtraction. It adapts to the shape of the wrist throughout the day, remains light under the sleeve, and doesn't retain sweat. It's designed for those who truly use their watch—not just to show it off.
Available in a selection of bold colors, each with a distinct personality. Not neutral catalog shades, but chromatic choices that say something.
Technical specifications:
- Material: 100% biodegradable bio rubber from sustainable sources
- Compatibility: Apple Watch (all models with standard attachment)
- Installation: quick release without tools
- Use: continuous, all day — gym, office, daily
- Available colors: wide range, vibrant tones
Note: The original product description does not include specific measurements in millimeters, thicknesses, or lug lengths. Complete dimensional specifications are available in the technical data sheet for each compatible Apple Watch variant.

ARTIGIANATO ITALIANO
Manifattura Milanese
Ogni cinturino è un pezzo unico, tagliato e cucito a mano nel nostro atelier di Milano. La tecnica della cucitura a sella garantisce una resistenza superiore, mentre i bordi sono rifiniti con sette strati di tintura applicata a pennello, assicurando una longevità che sfida le tendenze passeggere.

How does this bio rubber react if I wear it every day under stress? Will it degrade in a month or does it really hold up?
It's designed for continuous use — gym, office, all day without breaks. The material behaves like technical rubber, so it handles daily stress. What differs from standard rubber is that at the end of its useful life it disappears without a trace, because it comes from renewable sources. It's not a choice that costs you durability: it's a strap you use while you wear it, then it dissolves when you don't need it anymore.
I've tried rubber straps from other brands and after two weeks they rot from sweat underneath. This one doesn't, I assume?
No, it doesn't retain sweat. The geometry is essential, with no parts that create moisture pockets. It stays light under your sleeve and dries quickly because the material is engineered for this — it's one of the reasons this strap exists instead of using the usual silicone everyone does.
How easy is it to put on and take off? I don't want to complicate my life with tools every time.
Quick release without tools. You take it off and put it back on with your hands, like the original Apple strap. There's nothing complicated about it: it's one of the prerequisites of this work.
What colors do you have? I was reading ‘vivid tones, nothing neutral’. I need to know if there's a decent black or if they're just strange colors for effect.
The range is wide and the color choices are deliberate — each one has a precise personality, they're not neutral off-the-shelf options. But the specific colors available right now you'll find in the product sheet for your Apple Watch model. What I can tell you is that we're not chasing effect: we're looking for colors that actually work on your wrist.
I have a relatively new Apple Watch. Will this strap definitely fit or do I need to check the model before ordering?
It's compatible with all Apple Watch models with standard lug attachment. But to have the exact lug width measurements for your specific version — whether it's 40mm, 41mm, or others — check the technical sheet of the variant you're interested in. You'll find everything you need there to be sure about your purchase.
