Handmade Straps
Apple Watch Bio Rubber Strap Red — Made in Italy
€45,00
Organic rubber, not just any rubber. The difference lies in what remains when the strap has served its purpose: nothing, by choice. One hundred percent biodegradable, produced in Italy with a process that considers the end-of-life of the material already during production.
The red chosen for this version is not a timid red. It is sharp, recognizable, designed for those who wear the Apple Watch as an item of character—not as a neutral accessory to be forgotten on the wrist. At the gym or in a meeting, the color plays its part without asking for permission.
Bio rubber has a tactile feel that standard silicone cannot match: softer in flexibility, quieter on the skin. The ergonomics are built for prolonged wear—no localized pressure, no irritation even on the longest days.
A strap that compromises nothing: neither daily comfort nor the conscience of those who choose it.

Tell me honestly: after how long does it start to degrade? Because if I take it off and put it in a drawer for six months, I don’t want to find a sticky piece of rubber.
That doesn’t happen on its own at home. It’s one hundred percent biodegradable, but what matters is context: bio rubber degrades when exposed to the right conditions — humidity, bacteria, microorganisms in soil. In your home drawer the strap stays intact. The material itself is designed to return to earth without a trace when its cycle truly ends. The difference between this and silicone is that bio rubber won’t still be alive in a landfill a hundred years from now.
Is the red really what I see? Because in product renderings online the color shifts depending on the lighting and I don’t want to receive a pale orange or dark burgundy.
The red chosen for this version is not muted or timid — it’s sharp and recognizable. It’s not an orange, it’s not a burgundy. If the goal was a color that shows itself immediately, that doesn’t disappear on the wrist, this is it. Material rendering is matter, not photography: bio rubber has a texture that absorbs light differently from the glossy silicone of standard straps, so the color has different depth. But the base tone is the one you choose consciously, not a surprise.
Why does bio rubber cost more than silicone if it’s ‘just rubber’? What difference do I actually feel on the wrist, beyond the green story?
Because bio rubber is not silicone — the process to produce it without compromise on biodegradability costs. The difference at the touch isn’t narrative: it’s softer in flex, quieter against skin. With silicone you feel that light rustle, that micro-friction. With bio rubber there is no micro-friction. For extended wear, hours and hours, what you won’t feel is localized pressure. It’s not softer just as marketing: it’s engineered ergonomically to not irritate even on long days. Touch someone else’s strap to understand the difference.
I’m fine with it being biodegradable, but in the meantime I want it to last. If I use it every day at the gym plus two weekly swims, how long will it hold before it starts losing shape or color?
It’s engineered for daily use, sports included. The red is a color chosen precisely because it holds — it’s not a pastel destined to fade. If you wear it at the gym and in the pool, bio rubber doesn’t degrade from this; soil notices it, not your wrist. Shape loss over time happens to any strap, but the ergonomics here are built to not put pressure on you even after weeks of continuous wear. As for precise durability — how long before you decide to change it — that depends on how you treat it, not on an intrinsic flaw in the material.
Standard Apple Watch attachment means I can swap it with straps from other brands or previous versions? I want to avoid getting locked in.
Yes, it’s standard Apple Watch attachment. You swap it without issues with any other strap compatible with the same Apple Watch. You’re not locked in — you can alternate it, try other materials, go back. It’s just a choice that remains a choice, not a lock.
