This was used when I bought it and I bought it for the gold matrix module. I switched the 3421 module from this watch and replaced it with a 3421 module from the dw5035 in the last picture. So it is still a 3421 and it is still a 35 anniversary module but it is a light mirror gold color. If you have any question about this please reach out to me. It is used and it shows its age but it’s a Casio and will last for a long time!
