Introduction

Use this guide to remove the back cover assembly on your TicWatch Pro 3 GPS.

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

Tools

Step 1

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

Step 2

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

Step 3

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.

Step 4

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.

Step 5

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.
