Our smart watches, fitness bands, and screenless smart bracelets are fully compliant with the European Union CE RED Directive (2014/53/EU), covering Radio Frequency (EN 300 328), Electromagnetic Compatibility (EN 301 489), and Health & Safety (EN 62368-1). Additionally, products carry RoHS 2.0 (2011/65/EU), REACH skin-contact allergen safety approval, and official UKCA certification for distribution across England, Scotland, and Wales. Full Technical Construction Files (TCF) are available upon signing an NDA.

For standard OEM orders (which include custom silk-screen laser logo engraving on the back plate, custom startup display logo, and customized retail color box design), the baseline MOQ starts at 500 to 1,000 units per model. For deep ODM development—such as opening custom plastic or zinc-alloy injection molds, modifying PCB component placement, or developing unique woven strap materials—the MOQ typically starts at 3,000 to 5,000 units depending on tooling complexity.

Yes. We specialize in enterprise-level software enablement. We supply comprehensive native iOS (Objective-C / Swift) and Android (Java / Kotlin) Software Development Kits (SDKs) along with comprehensive API documentation. This enables your internal software team to connect via Bluetooth Low Energy (BLE), parse hex data streams for heart rate, step telemetry, HRV data, and battery status directly into your enterprise cloud software, completely bypassing standard consumer mobile applications.

Each sealed smart device chassis undergoes a multi-stage air pressure and vacuum decay test using automated pneumatic testing equipment prior to module assembly. Selected statistical samples from every production lot are subsequently submerged in a pressurized water tank at a depth of 1.5 meters for 30 minutes (conforming to IEC standard 60529) to verify zero fluid ingress.

Standard factory samples without customization ship within 2 to 4 business days. Custom branded pre-production samples (with laser engraving and custom packaging proofing) require 7 to 10 working days. Upon sample approval and deposit confirmation, full-scale mass production lead times range between 20 and 28 calendar days, depending on order volume and component sourcing timelines.

We maintain an industry-leading factory defect rate below 0.15%. All B2B manufacturing contracts include a standard 12-month to 24-month quality guarantee. For bulk order shipments, we provide 0.5% to 1.0% spare units or key components free of charge to cover potential transit damages or immediate customer replacements. Alternatively, verified defective units are credited or replaced in the subsequent production run.
