Disassembly/Repair of the mobile device Garmin Fenix 5 with each step description and the required set of tools.

🛠 Difficulty: 🟢⚪️⚪️

⏰️ Disassembly time: 20 minutes

A Fenix 5X watch came in for repair. This is actually the first time we’ve had a Garmin product on the workbench 😊

We had only heard that these are watches made for professional athletes, well-protected and packed with features.

We unscrew five screws from the front of the device.

We lift the display module.

It opens easily because there’s no adhesive around the display perimeter.

The liquid ingress protection is provided solely by a rubber gasket surrounding the edge.

This is similar to what we’ve seen on budget smartwatches from Huawei. However, Huawei’s water resistance is only rated for up to 1.5 meters of submersion—whereas Garmin claims up to 100 meters (10 ATM) for this model 🧐

We disconnect the display module’s flex cable and set it aside.

The display module itself is quite unusual—it’s our first time seeing a polygon-shaped display on a round watch 🙂

We remove the antenna from the housing; it’s not fastened by anything.

We unscrew a couple of screws securing the main board inside the housing.

We disconnect the flex cable for the sensors.

We remove the main board from the watch casing.

The battery is attached to the back of the main board using double-sided tape and is connected to the board via a wired connector.

What’s left in the housing is the sensor flex cable and, at the top, spring-loaded charging contacts.

By the way, the four screws on the back of the watch are purely decorative—you can unscrew them, but they don’t hold anything in place 🙃
