I got this watch now and can share some technical details (and reveal some trickery):
- The display is the same 1.6" 400x400 ST7797 like all the other watches.
- Both cameras are 2.0MP model BF2206.
Edit, some of the positive remarks:
- The buttons looks to have a different design that hopefully prevents the LEM12/Prime problem.
- The touchscreen uses a ITE controller and has a smaller ‘deadzone’ at the edge.
- Compatible with the other C7S firmware (system.img).
