I have been having issues with transferring data to my pc, the watch is intermittently recognised. On inspection I noticed that the metal connection dots on the watch are wearing out and causing this fault. If I grip the watch and connector tightly then I can force a good contact. What's the fix here? It would seem that the process of attaching the data cable to the watch is eroding the contacts...... Not a good situation, highly frustrating and I cannot rely on Bluetooth transfer. Your advice please.
