What happened and what’s the exact problem @TKL? Photo of your Riseman would be cool as well... Thanks in advance and I m sure we can figure it out ....
Totally my fault, as I cleaned the debris off the front of the sensor after cleaning the Riseman.
It's the only watch I have with an altitude and barometric features so didn't know that the debris should be left well alone.
Think the only way to fix it is to replace if they are available that is.
Here's a couple of pics.
