What is the minimum order quantity (MOQ) for OEM smartwatches?

We work with three MOQ tiers. White-label starts at 300 pcs for smart wearable jewelry and 500 pcs for smart rings, ECG smartwatches and 4G smartwatches. OEM custom branding starts at 1,000 units for smartwatches (2,000 for smart bands and TWS earbuds, 1,000 for AI smart glasses, 500 for smart rings). ODM full custom development starts at 3,000 units. Logo-only engraving is available from 100 pcs.

Which certifications does the factory hold?

We hold 8 self-owned certifications: ISO 9001:2015, CE (RED), FCC Part 15, RoHS, REACH, WEEE, CA Prop 65 and GCC. FDA 510(k), EU MDR and ISO 13485 are assist-customer services only; we do not hold these certificates ourselves. Bluetooth SIG/BQB is not claimed as a factory-held certification.

How do you control quality and what is your defect rate?

Every batch passes a 4-step QC process: functional testing, screen inspection, 48-hour battery aging and waterproof pressure testing. Our standard mass-production defect rate is below 0.3%, compared with a typical industry range of 2–5%. Our best single verified order reached 0.12%, which is not presented as the standard rate.

Can you customize firmware, watch faces and the companion app?

Yes. Our 70+ R&D engineers handle firmware, UI/UX, custom boot logos, watch faces, health algorithm tuning and white-label companion apps. Hardware changes such as PCB layout, sensors, casing and molds are handled under ODM projects.

Who owns the intellectual property of a custom project?

100% of the IP for custom designs, molds and app assets belongs to the client. We sign an NDA before technical discussions and never resell or replicate client designs.

Do you ship worldwide and support Amazon FBA?

Yes. We export to 50+ countries under FOB, CIF, DDP and EXW terms. Our Amazon FBA DDP service covers the US, EU, UK, Japan and Australia, including FBA prep, labeling and customs clearance, with typical transit of 10–18 days.

What is the difference between white-label, OEM and ODM?

White-label adds your logo and packaging to a proven existing model. OEM adds custom branding, packaging and software on an existing hardware platform. ODM is full custom development including hardware, PCB, molds and exclusive functions, with 100% IP ownership for the client.

Are your smart wearables medical devices?

No. Our wearables are consumer wellness devices. Health data is for reference only and must not be used for diagnosis or treatment. ECG models can flag irregular rhythms as an early indication but cannot detect a heart attack. For medical-grade programs, our compliance team supports clients with test reports and registration documentation.

What warranty and after-sales support do you provide?

All products carry a 12-month manufacturer quality warranty, plus spare parts supply, multi-language technical documentation and a dedicated after-sales team. Buyers in the EEA, UK and Switzerland also benefit from the 2-year statutory consumer guarantee required by local law.

Strategic Market Insights

Belgium's Evolving Demand for ECG Fitness Wearables

Belgium stands as one of Western Europe’s most sophisticated health-tech markets. Driven by high digital health adoption in Flanders and Wallonia, alongside national preventative healthcare policies supported by the RIZIV/INAMI framework, Belgian consumers and enterprise buyers are increasingly transitioning from basic step-counters to advanced, cardiac-aware smartwatches.

For electronics brands, healthcare distributors, and corporate vitality suppliers in Brussels, Antwerp, Ghent, and Liege, offering continuous ECG (electrocardiogram) and PPG (photoplethysmography) tracking provides a clear competitive edge over standard consumer fitness bands.

Key Belgian Buyer Trends:

Active Endurance Sports Culture: Flanders’ deep-rooted cycling heritage and Wallonia’s trail running movement demand high-precision heart rate zone monitoring and sudden arrhythmia detection under heavy physical strain.
Aging Demographic & Telehealth Integration: An expanding senior population across the Kingdom requires comfortable, 24/7 cardiac rhythm check-ups with downloadable PDF ECG reports for general practitioners (GPs).
Corporate Vitality Programs: Major enterprises in Brussels and Antwerp offer corporate wellness perks, preferring multi-lingual (Dutch/French/English) companion apps.

Engineering White Paper

Industrial ECG + PPG Architecture: How We Achieve Precision

In consumer-grade health wearables, accurate Electrocardiogram (ECG) detection requires overcoming low signal-to-noise ratio (SNR), skin impedance variations, and motion artifacts during active movement.

Single-Lead Dry Electrode Design

Utilizing medical-grade 316L stainless steel or titanium nitride coated bezel and bottom electrodes. Engineered specifically to minimize skin-to-metal resistance, delivering a clean biopotential ECG microvolt trace without requiring conductive gel during 30-second spot-checks.

High-Frequency AFE Sampling

Integrated Analog Front-End (AFE) sampling at 250Hz to 512Hz. High sampling rates enable precise extraction of P-wave, QRS-complex, and T-wave intervals, allowing companion app algorithms to flag irregular rhythms such as Atrial Fibrillation (AFib) and premature contractions.

PPG + ECG Dual-Fusion Filtering

Combines optical photoplethysmography (green + infrared LEDs) with biopotential sensors. Our proprietary firmware cross-checks pulse wave velocity (PWV) against electrical heartbeat signals to filter out false positives caused by arm vibrations during cycling or running.
