* The thickness of the watch will be reworked in the next version of the casing, the goal is to shave 3 to 4 mm off to reach 12 to 13 mm.
* I also designed a docking station for which is used to :
* Recharge the W800 Smart Watch by simply putting the watch on it. The connection between the docking and the watch is done through a magnetic 4 pin connector.
* Flash a new firmware to the watch. No extra programming hardware is required, only the docking is needed.
