Garmin Vivomove HR - oled screen is not working

"I am not able to paar with BT, because I can’t see BT access number.

I wrote to Garmin Support and now I am waiting for any feedback.

Update.

I got feedback from Garmin that they have no support and no possiblity to repair.

So I decided to diassembly my Garmin and I opened it.

Unfortunately screen is broken, no possible to replace.

But for example model of battery is IL38FM08ABT17.

89mAH, 0.34Wh, voltage 3.8V. Battery is LI-ion.

It is not easy way of replace it, but it is possible.

Unfortunately I didn’t find this battery on the market."

how did you dissamble it?. i have moisture inside it and i would like to open to dry it.

My first watch was slipped in water and permanently disabled to work as it was fell in water for 30 minutes. Then I have purchased an other one which is showing moisture in it and that’s why sometime I worried about it. Will it also be damage my watch?
