    • Remove the seal around the circumference of the watch casing, as you will be handling the casing a lot and you don’t want to risk tearing the gasket.

    • Using the tweezers, remove the circlips around every button very carefully.

    • When the circlips are removed, you can pull the buttons off. Do this step carefully because you will also find a return spring inside every button hole

    Beware of losing the circlips especially during reinstall. Replacements are $10 USD/50 count. See below.

    • Clean the case, including the hole of the buttons

    • Clean the buttons and the springs

    • (OPTIONAL) You can lubrificate the buttons before re-inserting them in the case

    • Reassemble the watch

    I have a 5X that needs the battery replaced. it would be great to add the battery replacement to this guide! any chance you could do this ? I purchased the battery already and am ready to do this. Garmin says too bad too sad my device is "end of life" I simply refuse to believe that. It's a $800 device and although it's old(ish) the only thing wrong is the battery.

    Samuel Prokop -

    I Samuel,

    Unfortunately, I don't have a Garmin 5X but I've found a video on YouTube that can help you replace the battery: How to replace your aging Garmin Fenix 5X Battery

    What is the best lubricant for the buttons? I'm leaning toward a silicone spray, but that may not be too durable.

    Dante Horatio -

    I decided on graphite so it won't gum up and can be easily powered in to reapply.

    Dante Horatio -

    Buenas tardes, me ocurre este problema con mi Garmin fénix 6x saphire. El procedimiento sería el mismo?

    Jose Antonio Cordero Hernandez -

    Hola buenos, en caso de haber perdido uno de los tornillos de la parte delantera del cristal como o donde puedo reemplazarlo? Gracias!

    Erik -

Conclusion

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

Thanks for that info. In looking at the pictures, I can’t tell which piece is the battery. Do you think it can be easily replaced? Or is it soldered in? Thanks.

Patrick Chang -

Hi,

the battery is visible in the step 5 and step 6.

It is linked to the mainborad with a connector, It’s not soldered.

It’s glued to the back cover but, in my opinion, it can be easy replaced.

The battery type is "361-00097-00"

The nominal specifications are 255mAh, 0.97Wh and 3.8V

On ebay you can find a new battery: https://www.ebay.it/itm/283519139846?has...

I hope this can help

Garmin Boy -

Maybe do You know where to purchase a gaskets?

Edgaras Tamošauskas -

Unfortunately, I don’t know where you can find it.

I’ve searched on my favourite websites with no luck.

Garmin Boy -

Question: do I need to disasassemble the screen to change only the battery? Can I just access to it by the rear cover?

Thanks for the info!

Cristóbal Sabroe Yde -

Hi,

Yes, I think you can remove only the rear cover.

But if your watch is 2-3 years old, I think that cleaning everything it’s worth it.

Garmin Boy -

Anyone that has done a tear down of Fenix 6? The vibration module is loose and would be good to see if it can be glued back.

Ludde Algell -

Hello, thank you for the article. Is there anyway to clean the button on the motherboard (especially when oxidized)? Some sort of solution or lubricant? I think some seawater snuck into the case (through the button) while pressing the back button under water. I followed your steps to de-assemble the watch and I think the button is somehow stuck, resulting in a kind of random/continuous activity. Thank you. Jacopo

Jacopo De Santa -

Hi Jacopo,

I suggest cleaning it with isopropyl alcohol or rubbing alcohol. Another solution is to use a mixture of baking soda and water. You can apply the solution using a small paintbrush.

Beware of the circlips: They are easy to lose. (Whoops. Twice.) I bought a replacement here (the 1/8" stainless steel): https://www.mcmaster.com/catalog/130/374...

Dante Horatio -

CORRECTION: Buy the 1/16" size! Then, crimp them before fitting them back on the shaft of the button so they are tight.

Dante Horatio -

The screen of my garmin fenix 5s plus is malfunctioning. It displays horizontal lines only. Do you know if can be repaired?

Jes -

Hi Jes.

Unfortunately, I don't have this information.

However, I think that I'll probably have to change the screen.
