Some ideas are in the design:
- Slide in Mi Band 3 into the adopter which mounted on band of watch.
- Slide/Clamp into the adopter which mounted on the watch
- Slide/Clamp into the adopter which mounted on the band of watch
- 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.
26 May 2019 update:
Improved adopter was designed to reduce the gap and fit the size of Mi3 core unit.
Integration of Digital onto Mechanical Watch
I just want to use my Mi3 with automatic winding watch.
This is only a simple option for the adopter without any locking mechanism to a nylon watch band around 20mm width. It can be modified to fix onto steel watch band or add a clamp such that your Mi3 can be read in parallel with your watch but not at the back of band.
