Built to clip, made to last.
Every KLIP'S piece is produced in small batches in the European Union from materials chosen for skin contact, durability, and colour stability. Below is the full composition we publish — no surprises, no hidden additives, no proprietary blends we refuse to name. Where we use a trademarked material we say so; where we use a generic material we say so too.
The case dress-up
- Material: bioceramic — a sintered blend of approximately 65% zirconium dioxide (ZrO₂) and 35% high-performance polymer (PA12 base), pigmented in mass.
- Pigments: mineral oxides, RoHS and REACH compliant, no heavy metals above EU thresholds. Each colour uses between two and five pigments, blended in our Paris studio before being shipped to the EU sintering plant.
- Inner ribs: medical-grade thermoplastic elastomer (TPE), latex-free, hypoallergenic.
- Diameter / thickness: 41.0 mm × 1.6 mm added thickness over the original watch.
- Weight: approximately 8 g per shell.
- Surface finish: matte, micro-bead blasted, Mohs hardness ≈ 7. Scratch-resistant in normal daily wear; will mark if dragged across granite or steel files.
- Country of moulding and sintering: European Union (Italy / Germany depending on batch).
Bioceramic — what the word means
"Bioceramic" is not a regulated term. We use it the same way Swatch popularised it: a sintered composite of ceramic powder (zirconia) and a high-performance polymer matrix. The ceramic gives the material its hardness and matte appearance; the polymer gives it the impact resistance a 100% ceramic part would not have. Our blend is 65/35 by mass — heavier on the ceramic side than most consumer bioceramics, which gives our shells the dense, "warm-cool" feel of zirconia rather than the plasticky feel of a polymer-heavy mix.
The material is biocompatible (ISO 10993-5 cytotoxicity tested), nickel-free, latex-free, and contains no bisphenol A. It is safe for direct, prolonged skin contact in healthy adult use.
The strap
- Composition: 78% recycled polyamide (PA6 from post-industrial fibre), 22% elastane.
- Construction: circular knit, seamless, no metal hardware.
- Closure: slip-on, no buckle, no clasp, no metal pin.
- Wrist range: 14 cm to 21 cm (one size).
- Certification: OEKO-TEX® Standard 100 (Class I, suitable for direct skin contact including babies under three).
- Weight: approximately 9 g.
- Country of knit and finishing: European Union (Portugal).
Care — the strap
- Machine-washable, gentle cycle, cold (≤30 °C), inside a laundry bag.
- No fabric softener (clogs the elastane).
- No tumble dry, no radiator: lay flat on a towel.
- If it stretches with daily wear, a 30-minute soak in cold water restores 90% of the original tension.
- Lifespan in normal daily wear: 18 to 36 months.
Care — the shell
- Wipe with a soft damp cloth. Microfibre is ideal.
- Do not use solvents, alcohol, acetone, ethanol-based hand sanitiser, or abrasive sponges. They will dull the matte finish.
- Avoid prolonged exposure to perfume, sunscreen and chlorine.
- For deep cleaning: lukewarm water with a drop of pH-neutral soap, rinse, air-dry.
- Lifespan in normal daily wear: indefinite. The bioceramic does not fatigue.
What we do not use
No PVC, no phthalates above EU REACH limits, no chrome VI tanning, no bisphenol A in any part of the product or packaging. Our shipping mailers are 100% recycled paper, FSC-certified, with water-based ink. Our internal protective sleeves are made from a single grade of recycled polyethylene (LDPE 4) — fully recyclable in standard EU plastic streams.
We do not use animal-derived materials. KLIP'S products are vegan by default.
Allergens and skin safety
The bioceramic shell never touches your skin in normal use — it sits on top of your watch, not on your wrist. The strap, which does touch the skin, is OEKO-TEX certified and free of the most common contact-dermatitis triggers (latex, nickel, chrome VI, formaldehyde, dispersed dyes). If you have a known elastane allergy, do not buy our straps.
End-of-life
The strap is recyclable in textile streams that accept polyamide blends (most EU municipal collection points). The bioceramic shell is not recyclable in standard streams: bring it back to us in a stamped envelope (address on request) and we will grind it down for use as a filler in the next batch's polymer matrix. We do not run a formal take-back programme but we honour every shell returned for recycling with a thank-you postcard.
Documentation on request
For B2B buyers (resellers, gift companies, hotels): full REACH SDS, OEKO-TEX certificate number, and ISO 10993-5 cytotoxicity report are available on request to hello@klips.watch. We are happy to provide the underlying paperwork to anyone who needs it for a procurement file. See also the concept and compatibility pages for non-material specifications.
