Hello, I was hoping this Reddit could help me out with this watch inherited from my late grandfather as I was directed here from r/watchrepair

I was quoted $200 to fix these link pins as they were a special type, and had to be specifically ordered. I don't know if I'm being taken for a ride, so figured l can order them and fix it myself.

I essentially need the one pin for this as it's gone missing and I don't have any spare links to salvage from. Would anyone know what type of pin I need, and where could get these pins from?
