Resurrecting a DEAD SEIKO SNA411 Flightmaster With a Fried Circuit Board

I bought a used Seiko SNA411 Flighmaster without knowing its circuit board was completely fried due to battery leakage. Whoever sold it to me rescued it from an old drawer and told me I only had to change the battery. Despite seeing all the leakage and the corrosion, I still tried to do a battery change. Obviously, that didn't work, so I went down the rabbit hole of watch restoration.

I changed the original circuit board for a YM62 circuit board made by Epson. It's exactly the same circuit board, and Epson makes it for other watches.
