Introduction

Use this guide to replace the daughterboard in your TicWatch Pro 3 GPS.

You’ll need replacement adhesive when reassembling the device. Your device will function normally, but will lose its IP (Ingress Protection) rating.

    • Before starting repairs, take your watch off the charger and power it down.

    • Remove the watch band.

  2. LWbfEUyt33T3cNNg

    • Use a Torx T3 screwdriver to remove the four 4.1 mm-long screws securing the back cover.

  3. kOKfWXIjOdEqYBkX

    • Apply a heated iOpener to the rear side of the watch for 5 minutes to loosen the adhesive underneath.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.

    • Insert the flat end of a spudger into the microphone opening at the top edge of the back cover.

    • Pry upwards to loosen the back cover assembly. This may require some force.

    • Don't try to remove the back cover assembly all the way yet. It's still connected to the daughterboard.

    • Swing the back cover assembly open by 45 degrees to gain access to the sensor assembly cable.

    • Use a spudger to disconnect the sensor assembly cable by prying the connector straight up from its socket.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

To reassemble your device, follow these instructions in reverse order.

During reassembly, apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.

Where can I buy a daughterboard?

Alex Krizski -

For those of you with button problems you can see the tactile switches attached... Mobvoi does not sell this part or any part.
