Black Screen on new watch

• Cable going out East (towards the buttons) as per the sticker on the cable (which is the only way it was ever connected anyway)
  
• Cable works fine with December version of the watch (which still works fine, other than the ring that broke off and was glued back on).
  
• New one was way better though as it reliably allowed me to connect remotely to it whereas the early version had lots of issues with that
  
  

Also the one moment it DID come on (while it was connected to the USB battery) it showed > 50% battery. The moment I disconnected the screen went black. I would assume a hardware issue with the display if BLE still worked.

What is the BLE MAC range of the watches ? I could check whether BLE is showing up when scanning via phone, which might indicate a display issue. It is not connecting via the normal means though.
