8. Complete final bonding only after all functions have been verified.

Battery replacement

1. Open the watch using appropriate precision tools.
2. Disconnect the battery before handling other internal components.
3. Carefully remove the battery without bending, puncturing or compressing the cell.
4. Compare dimensions, flex cable and connector with the replacement part.
5. Install the new battery.
6. Test power-on and charging before final reassembly.

Rear housing or rear module replacement

1. Open the smartwatch and disconnect the power supply.

Compatibility and Versions

The confirmed technical reference for the Huawei Watch Fit 4 Pro is SYA-B29.

It should not be confused with the standard Huawei Watch Fit 4. Although both devices belong to the same generation and have a similar external design, hardware and construction differences may affect displays, batteries, housings, rear covers and internal components.

The Huawei Watch Fit 4 Pro SYA-B29 measures approximately 44.5 x 40 x 9.3 mm. Components from other Watch Fit models should therefore not be considered compatible solely because of their similar appearance.

Before removing protective films or applying adhesive, always check the SYA-B29 reference, dimensions, flex cables, connectors, mounting points and internal layout.

Differences Between Spare-Part Quality Grades

Compatible:

A cost-effective option intended for repairs where reducing component cost is important. Depending on the manufacturer, brightness, colour reproduction, finishing, materials or touchscreen response may differ.

Premium:

Replacement components selected according to tighter manufacturing, fitting and performance standards. Premium displays are intended to maintain the visual and touchscreen experience of the factory-fitted panel as closely as possible, particularly important for AMOLED smartwatches.

Service Pack:

Service-channel components supplied for the specific technical reference when available. This option is suitable for repairs where service-level specifications, materials and fit are prioritised.

The appropriate quality grade should be selected according to the customer's budget, labour cost and required repair standard.

Benefits for Professional Repair Shops and Service Centres

Correct identification using the SYA-B29 reference helps reduce ordering errors, incompatibilities and unnecessary returns. Professional repair shops, retailers and technical service centres can access dedicated repair components, wholesale pricing subject to commercial conditions, invoicing and technical support.

Displays, batteries and other internal parts should always be fully tested before protective films are removed, adhesives are applied or the device is permanently closed.

Opening the Huawei Watch Fit 4 Pro may affect its original factory sealing. Although the smartwatch is designed with water resistance from the factory, this should not automatically be considered restored after repair without an appropriate resealing procedure and water-resistance testing.
