Smart watches exported to EU countries must obtain CE certification. Because smart watches typically feature wireless communication functions such as Bluetooth and Wi-Fi, they fall within the scope of radio equipment and must therefore comply with the CE-RED Directive (2014/53/EU, Radio Equipment Directive), while also meeting the requirements of the CE-EMC Directive (2014/30/EU, Electromagnetic Compatibility Directive).
In addition to telling time, smart watches usually offer one or more functions such as reminders, navigation, calibration, monitoring, and interaction, with display formats including analog hands, digital readouts, and images. Most smart watches on the market today come with Bluetooth and Wi-Fi, so they generally require RED radio testing, EMC testing, and electrical safety (LVD) assessment as a complete package.
Note: If the product contains no wireless functionality at all, only EMC testing is required. If it includes Bluetooth/Wi-Fi, then EMC + safety + RED testing is required. The exact test items depend on the product's actual functional configuration.
1. Block Diagram | Format: PDF
Describes the function and purpose of each part of the product. The chip models indicated in the block diagram must match those shown in the BOM, schematics, and internal product photos (the internal photos must clearly display the IC model text). The block diagram must fully present information on all crystal oscillator frequencies, the frequency ranges supported by each chip function, and the antenna location.
2. SCH (Schematic Diagram) | Format: PDF
A searchable text-based PDF file must be provided (image-only files that cannot be searched are not acceptable), and the diagram must not contain garbled characters. The schematic should show the connections between components on the circuit board and must include component specifications, chip parameters, and antenna information. A white-background version is recommended, with no hyperlinks attached to values, so that corrections can be made easily when inconsistencies with other documents arise.
3. Operational Description | Format: Word
Describes the operating principle of the sample, all functions supported by the chips used, operating frequency bands, and maximum power parameters. The chips and functions referenced must be consistent with those in the SCH, BOM, and block diagram.
4. BOM (Bill of Materials) | Format: Excel or PDF
Lists all materials used in the product and must include component name, model, parameters, reference designator, quantity, and manufacturer. The chips listed in the BOM must match the SCH, block diagram, and operational description, and the BOM reference designators must correspond one-to-one with the PCB Placement, SCH, and internal photos.
5. PCB Layout | Format: PDF
Shows the layout and routing of the product's PCB, which must be consistent with the actual PCB inside the product.
6. PCB Placement (Component Location Diagram) | Format: PDF
Shows the position of components on the PCB. It must match the PCB shown in the internal product photos and the actual components, and each component must be traceable to its corresponding position in the SCH.
7. Hardware / Software Version
The software version number refers to the version of the product's operating system; the hardware version number refers to the version of the PCB. The hardware version provided must match the version marked on the actual PCB.
8. Label
The label must include: product name, brand, model, rated voltage, rated current, the CE marking, the crossed-out wheelie bin symbol (WEEE recycling mark), the manufacturer's name, and the manufacturer's address. The indoor-use symbol depends on the product (note: for products explicitly restricted to indoor use, such as routers, this symbol is mandatory). If the customer does not provide a label design, the certification body can supply a standard template.
9. User Manual | Format: Word
Introduces how to use the product, its functions, and precautions. The first page must include the product name, model, trademark (all series models and trademarks must be listed if applicable), and the manufacturer's name, along with the product's functions, operating frequencies, and corresponding maximum power. The functions described in the manual must match the product's actual functions.
The user manual must also include EU compliance-related warnings, which may be added based on the product's actual functions. Common items include:
It is advisable to initiate certification planning at the product design freeze stage and prepare the technical documentation described above in advance. Ensure that the chip models and reference designators are fully consistent across the BOM, schematics, block diagram, operational description, and PCB drawings — this is the most common cause of rejection during document review. Selecting an EU-notified laboratory or TCB body for testing ensures the recognition of the test report and shortens the overall certification cycle.
