Bio Rubber Strap for Apple Watch – Everyday
€45,00
Biodegradable rubber is not a compromise. It's a technical choice with an ethical consequence.
This bio rubber strap was created in the Milano Straps Lab, where materials are chosen for what they do — not just for how they look. The 100% biodegradable bio rubber offers a lightness on the wrist that leather cannot always guarantee: no unnecessary weight, no irritation, no break-in stiffness. It slides into place and stays there.
White is not a neutral color. On an Apple Watch, it is a statement of formal cleanliness — it works with light and dark watch faces, with steel and aluminum. It changes with daylight. It stands out, without seeking attention.
For those who use their smartwatch all day long — in the office, at the gym, while traveling — durability is not an option. This strap is built for extended daily use, with a material that does not degrade its properties over time, despite being biodegradable itself. An apparent paradox, a real consistency.
Technical specifications:
- Material: 100% biodegradable bio rubber
- Color: white
- Compatibility: Apple Watch (all models with standard lug)
- Type: everyday sport strap
- Clasp: standard buckle
- Recommended use: daily, all-day
Note: shades may vary slightly from images due to the inherent characteristics of the material.

How long does bio rubber take to start degrading? I want mine to last years, not weeks.
Good question. The material is 100% biodegradable, but what that means is it *can* degrade under specific environmental conditions — not that it does while you’re wearing it. The construction is engineered for extended daily use without technical characteristics deteriorating over time. As long as you’re wearing it on your wrist, it remains stable. If it ends up in a landfill, then yes, the biological cycle begins. It’s the reverse of the usual dynamic: durability in use plus environmental responsibility in one piece.
I have a space gray smartwatch — won’t the white make my wrist look too clinical?
White here doesn’t function like a medical mask white. It shifts with daylight and works with both light and dark dials. On space gray, the contrast reads more as formal cleanliness than sterile — it really depends on how you style it. If your watch leans minimalist, the white strap is part of the statement. If that aesthetic isn’t your language, it’s probably not the piece for you.
Does bio rubber lose grip when sweating—gym, summer—or become slippery?
No, it’s not like leather that softens with sweat. Bio rubber maintains its grip even with moisture — that’s actually one of the reasons it works well for daily and gym use. It stays in position and holds there, even when you’re sweating. The material’s lightness means it doesn’t burden your wrist even when damp, unlike thick leather.
If tonalities vary piece to piece, how do I know the white in the photo is what arrives?
Variations are subtle and stem from intrinsic bio rubber characteristics — it’s noted in the product description. It’s not a flaw, it’s the nature of the material. If the white in the photo matches the tone you need, that’s your range. If you’re particularly sensitive to micro-variations, this is the moment to contact us before ordering and check what we have in stock right now.
I’m interested in using it beyond Apple Watch — is it compatible with other smartwatches or just Apple ecosystem?
It’s built for Apple Watch with standard lug attachment. We have no declared compatibility specs with other ecosystems. If you’re using a different wearable, I can’t promise it works. If you want to understand whether your smartwatch fits our standard, reach out with the exact model and we’ll figure it out together.
