Quick question: the two wire cables at the sides of the black foil (Step 18) are of any use? I have broken mine (both) while opening the watch, and I am wondering if I have to throw everything in the garbage (I was replacing the battery) or I can still use the watch after battery replacement (I have to order the battery yet)

Sorry for replying after such a long time: I have cut the smaller side wires (both, I'm very proud of myself ;) ), did you have any problems using the watch with such wires cut? It seems very difficult to find replacement parts for such components.
