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
Magnificent vintage watch
Is there any numbering between the bottom lugs?
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!
ole
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
ole
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..
Best
Ole
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.
Sorry for double post. The tool online says case from 56 and movement from 57.
Caliber 8521 (lig 10 1/2 sc aut kal whatever that means)
The case is 34,88mm! Digital calipers from next door
Thanks for showing Ole, first time i've seen a 35mm case in that
patttern...there just the question of the model ref now.......
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.
Thank you. I Will Ask on the forum!
