2. Slide/Clamp into the adopter which mounted on the watch
3. Slide/Clamp into the adopter which mounted on the band of watch
4. Clamp into the adopter and charging pins were extended to the case for a stand.

For all the options, charging method shall be considered. It is preferred to have wireless charging or even solar power. Please design.
20 Feb 2019 update:
A fastening clamp was designed to fix it on nylon band. Clamp shall be inserted into the gap of adopter after a suitable position in band is adjusted.

Improved adopter was designed to reduce the gap and fit the size of Mi3 core unit.
