拆解

简介

All screws shown are T4 Torx screws.

Note on waterproofing: it appears that Garmin has used rubber gaskets to waterproof the watch, instead of adhesives or other one-time-use seals. In theory, this means that your device should retain its waterproofing if re-assembled correctly. However, without official guidance from Garmin, this is not guaranteed.

    • Use a spudger to lift up the circuit board from the bottom until it loosens from the body.

    • Use the thin end of a spudger to lift up the back of the indicated connector until it comes free. The connector pivots at the tip so it's necessary to lift it from the back.

    • The connector may require some force before it comes free. Tilting the circuit board to apply pressure may be helpful here. Be careful not to damage the wires leading to the connector.

    • The circuit board should now be completely detach from the body. Set it aside.

    • Before re-installing the back plate, re-install the back plate gasket.

    • It's possible for the gasket to stick to the back plate during the removal of the back plate. If this occurs, remove the gasket from the back plate.

    • Locate the groove on the bottom of the watch body and press the gasket into it. The gasket and groove are not symmetrical so be sure to orient the gasket correctly.

Thanks for the teardown! How is the battery connected (if one needs to replace it)? And does the Epix Gen 2 follow the same teardown?

it uses a connector, no soldering required. You can see in step 5 that the white battery connector is being removed. The connector is also visible at the photos with the battery from step 6, 7 and 9.

It seems Garmin has made some model changes. My Saphire Pro Fenix 6 (titan) from December 2019 has a battery connector already and the replacement battery fits perfectly despite the cables being about 4mm longer.
