Hello everyone!
I had such a problem for the first time in June, after I bought in the mountains in the river. At first, he gave it to a third-party company for repair (since Suunto left Russia for political reasons). I fixed them, they worked until last week. I bought in the sea and again the same story as everyone above, a soft reset and they stop working.
I removed the back cover and found that if you turn off the loop button, the watch works great, it is worth connecting it slowly, so it becomes clear that the middle button works (as if you press it for a long time). That’s why no one can turn on the watch right away. In the case of fresh water, it seems to dry up and work, with salt water it is more difficult.
I’m thinking of getting to the buttons at all and cleaning them, seeing what the mechanism is. But I can’t pull the board out through the back cover. It feels like it’s out through the top. I’m afraid to make efforts, it’s still electronics.
Maybe someone knows how to disassemble the watch and take out the board?
