hey there I followed a youtube video on how to solder usb cable into the board, but the thing is when i opened the watch there was a missing pin where you are supposed to solder the data negative. will i sti be able to solder the cables and connect it on a pc? or i won't?

are there ways to do this?

Unless you are good at soldering and have a temp controlled iron you're very likely to damage the board. You wouldn't get 2nd chances and repairing the pcb will be all but impossible.
Pre-tin wires, use rosin core 63/37 lead base solder only.
Get a schematic, otherwise make sure the points are correct. You must be fast as excessive heat will likely damage the pcb pads...
