We are developing our own motorized microphone that will at eTimer's request, put the watch into the six standard test positions and gather performance data.
The picture is a CAD representation, but we have a functional prototype on the bench. There is still reliability testing to be done, but initial performance is encouraging.
It can also autonomously run through the positions in sequence or randomly to simulate life on a wrist.
There is also a built in BME280 that enables logging of temperature, pressure and humidity.
