Ethan- Open watch by unscrewing back panel
- Pull electronics assembly out
- Unclip the battery cover (stamped steel) from the screen chassis (white plastic) by lifting the 4 clips around the perimeter
- Remove the battery (might be taped onto PCB)
- Pull apart the PCB and screen chassis (white plastic)
- Remove the negative battery terminal contact spring from the PCB (just pull it off)
- Solder thin flexible wires to the terminals as shown
- Cover negative solder joint with tape to prevent short
- Reattach screen chassis to PCB (line up the alignment pegs and press gently together)
- Clip the battery cover back on, making sure you don't press too hard on the bare LCD
- I partially reassembled the watch, partially to protect everything, but mostly to make sure I don't lose any more parts. The back cover screws are very long, so if you just partially tighten them the wires stay comfortable.
