    Hello all,
    I have just given by a good friend a vintage Heuer Silverstone 110.313 (Blue) and I found that it wears a Caliber 11 and not a Caliber 12, as I expected. Is that possible or it was changed somehow during the past years?
    Many thanks,
    Leandros

    Hi,

    The Calibre 11-i (an updated version of the Calibre 11) ran through to around 1973, and overlapped the Calibre 12, which started in 1971. The Silverstone was launched in 1974.

    In modern times, you might say that this means your watch has the wrong movement, but I have heard of Silverstones with the Calibre 11 and I would expect that these timelines are close enough to mean that you watch likely has the right movement. It's true that most Silverstones have the Calibre 12 movement, but I don't think yours is automatically "wrong"

    Thank you very much! I intend to sell it, but the only proposal I have is for 3,000 euros, which I consider rather low, depending the condition that is mint!

    C11 is correct, looks a nice piece too. Is there any provenance with it at all?
    3000 is as you say a tad low in my opinion but yours does looks authentic.
