I found a Samsung SM-845U watch on a trail behind my house that appeared to be in good shape. This trail is frequented by local ATV riders, so I assumed the owner would pass back by at some point. Assuming it is weather proof, I planted a stick painted with dayglow adjacent to the trail and hung the watch on it. Now, three months later a maintenance crew has knocked over the stick/watch and I have claimed the watch as my own. I need charging specs for this thing to attempt to bring it back to life. A standard wireless Qi charger does not respond, but there appears to be charging contacts on the back. Does anyone have knowledge of the expected voltage to these contacts? AC-DC, voltage, current, etc. I tried 5 VDC with no response by either the watch or PS current draw. There is also the likely possibility that the watch is just dead.
