i have this watch nearly 3 weeks and now the epoxy dissolves. i have a hole allready over one sensor, meaning the watch isn't waterproof anymore.
look at this
Never had such Problems with my fenix 5x after 2 years.
Besides the mushy/sticky buttons, this watch is very poor manufactured.
I will return the watch and stay away from the product, i think this is no single case / issue.
Only Sweat and water touched the watch, also no accident from falling down or something like that.
