    Bob,
    It has V657-8120 followed by AO in a square. On the face, it says V657-9021.

    1. Why do they differ? Is the -9021 the face plate model # (this one is brown)?
    2. Is there a repair manual anywhere you know of for V657 series (I think I read it is part of the SKS mode line or maybe I’m hallucinating)
    3. What type of maintenance does this watch require?

    Thanks.
