Note—I just deleted the first post because I put the wrong reference in the title! This is my Serica 4512. I am the second owner, dated 2021, so no warranty left (Serica warranty is 2 years). This is a model from prior COSC certification, but keeping great time. I haven’t had it for too long, so no additional wear and tear. Excuse the pictures, but the sapphire is clean, minimal if any markings on the bezel or case. This bracelet makes it extremely difficult to show scratches. This was the “papers“ provided; I’m not sure if Serica usually supplies any other cards. Asking $750, CONUS only please. Let me know if you have any questions!
