Unbranded smartwatch charger

[Minsky7]

Hello everyone
Ive been given a smart watch, without a charger. I tried to look for the charger online, and i could not find one. I tried also charging it wirelessly, and it does not work. The port is made out of 4 holes in a straight line. I will upload a photo of the wach and the charger, and i will appreciate anyone who recognize the wath ir the charger that fit. Thank you all,
Minsky7

I've seen similar on a 'fit-bit' it could simply be contacts for USB... Power, Ground, Data+, Data- ... The tricky part though, is in what order to they connect? You could cause damage guessing.
