    Hi

    I got this from my uncles estate. Probably belonged to grandpa.

    Apologies for not having checked the serial no yet, have to get a tool.

    I cant seem to find any 8521 or 8531 pie pans with a screw down back lid. Any
    thoughts on which model?

    Appreciate it if you have anything to tell me about it

    Best Ole

    Thank you both..

    @catherine. No it doesnt seem to be any numbering.

    I cant find any pics of 648 with screw back or pie pan. But otherwise you may
    be right. Im waiting for a tool to open the case.. Will Get back with more
    info then.

    thanks!

    Sorry i confused you with the 648, forget that for now ( ooops) ...there was a
    steel lot earlier in the sixties with punched numbering is why i asked..just
    trying to ascertain how ref666 cased both may have been given the caseback on
    your example. Odd lot

    The pie-pan i'd consider to be by the by...a neat trick but likely not one
    that stood the model up to be initially offered...my memories a bit sketchy
    nowadays..i'm sure there's an enamel dial paired with exactly that design of
    case...which sort of implys ' special order '.

    Please do return with the opening results, thanks for showing.

    I seem to recall a story ( cannot recall who told it) of a schaffhausen
    official putting together a gold automatic watch for himself...that owned this
    ^ style of 666 caseback....not that suprising really, i doubt schaffhausen
    would knock a customer back if they wanted a gold ingenieur minus the
    ingenieur.

    interesting story, which could explain the mix of parts. I Wonder how that may
    have
    happened in my grandfathers case..

    Would IWC have records of such a watch?

    What i think isn't conclusive just yet...

    If it is the case seen on the ref 666 then it is not a mix of parts...we've
    just been conditioned to call that case an ingenieurs case because it's seen
    to be done, Schaffhausen would'nt look at it like that. An 18kt waterproof
    auto would have been quite a purchase and likely not by an ingenieur or by
    someone wanting ingenieur written on the face....it could be seen to be a
    demotion...pie pans, email and cloisonne would have the opposite effect.

    Your grandfather touching for the watch may have more to do with what country
    he was in.

    Schaffhausen will know if the movement went into a gold case and who and when
    the retailer was. From memory i dont think the gold ref 666 was ref stamped.

    My grand father, Norwegian born 1902, went to Cornell for a while studying to
    be an ingenieur. He had to return early to be the breadmaker of the family
    though. Then started a succeful translating business in Oslo.

    Maybe ingenieur on the dial would feel very wrong to him since he never got to
    finish his studies..

    Again, youre insights are very much appreciated

    Would Schaffhausen be willing to check the history? I recall seeing a fee of
    300 chf somewhere.. Rather a lot..

    thanks

    Could i trouble you to measure the diameter please ole....between 3 & 9 in
    mm...the difference in cases will be slight usually somewhere between 34mm and
    36mm ( you may need to pull the crown to get an accurate measure)

    Of course!

    I dont own calipers, however Ive used three different rulers and estimate it
    as 35mm..

    The plot thickens ( smiley face)

    If you do get to a watchmakers to open the back (i'm pre-presuming there is no
    model ref nmb inside) then ask about calipers...36mm
    fits better with what i've been talking about...smaller size in that pattern
    is not anything ive seen or heard about before but that's all it means.

    Thank for your interest and help Catherine. Maybe the only way to get an
    answer is asking IWC. However 300 chf may be a large portion of the value ;)

    It's enough money....

    It may pan out that the type of screwback did'nt warrant a seperate reference
    to a more commonly seen snapback waterproof case and that the anomaly with
    regard the pattern was little to do with schaffhausen and more linked to the
    suppliers and trends within the industry at exactly this point in time,
    schaffhausen do have form for having two aesthetically different casebacks
    shareing the same reference.

    The pie-pan dial could also be discounted in searching for a ref, , ive lost
    track on this site ( to guide you) but if you request the old catalogues from
    around '57 ( i'm sure a member will oblige) and look at examples containing
    that 666 type case middle and then use your diameter to scope further...you
    should be getting warm.

    Enjoy the hunt.
