7545

Hi everyone, I am learning about the 7548 and 7C46 movements. I see where some claim the 7C46 is an all metal movement. I have seen one and I know that is not true. Are they confusing the 7548 with the 7C46? Also, why did Seiko replace the 7548 with the 7C46? From what I understand after...

Hi, I am looking for a new movement for my 6309 project, please let me know what you have. Thanks [email protected]
