152xxxx serial puts it late 66 and the case back has a IV67 stamp. Watch has wear marks on case, crystal, insert, bracelet, and case back. Pics represent condition well.
Has a later glossy dial with dead lume but hands are still active and so is the pip which has cracks. I assume the bezel insert is later as well.
Bracelet is late 90s U code solid link 93150 with 501B end inks and in pretty good shape.
