[Q] Help me to find out +5 pin

Dear all,

I lost my cradle and my watch totally powered off now :(
I have a plan to buy a replacement cradle, but I prefer to make a handmade cradle. :D

Can someone check where the ground and +5 pin is?
Please take a look this picture (picture credit goes to @phinal post)


By my guess, GND at pin number 1 after contacting watch body using a multimeter. CMIIW.

Thanks for your help.
