Need Help Indentifying an Heirloom, Please

Hey Everyone,

First post here. Recently I was gifted a watch from my great grandfather and
am hoping to date/identify this gorgeous (and fully functional) piece,
please.

Congrats on a very nice watch.

In order to date the watch, you'll need the case and movement numbers.

Cheers!

Thanks for the reply, @Mr. Terry Russel. Sorry for the dumb Q, but what is the
easiest way to get said numbers? (I presume by opening the case.)

Yes, the watch will need to be opened. The case number will be inside the
cover and the movement number will be engraved on the movement itself, usually
near the balance wheel. Assuming your watch has a pressure fit back, you might
want to get a watchmaker to remove it. It's not difficult unless youve never
done it, in which case you can scratch the case or jab the tool into your hand
(ouch!)

Regards

Terry

Thank you very much. I'll reply to the thread once I have said info.

Very nice IWC watch

It is either Caliber 83 or 88.

Cal 83 was in production from 1930 to 1947 And Cal 88 from 1946 to 1964

Thanks for the nod and help, Mark.

It's probably a Ref 410 with a cal 83 movement

Like this one.

Hi All. I was finally able to have the case back removed. Please find attached
images for reference. Would love help identifying exact year, make, model,
value,
etc.

Beautiful watch and I can confirm it is Cal 83.
The caseback number gives a manufacture date of approximately 1941.

You now have enough information to research The Internet of Things for a
value.

Thanks so much, Mark. Apologies as I'm new to IWC, but is there a particular
model name or number? Moreover, is it possible to discern where this might
have been manufactured, sold, bought, or if it's solid gold or just plated? (I
promise, I'll soon run out of questions.)

Esteemed member Clepsydra gives you a possible reference number for this
model. Please scroll back up, for his previous post.

IWC sometimes stamps the number in the case back and sometimes not, which is
the case with your watch.

The only way to tell the model number is to compare with period catalogues,
which is a tedious process. These watches, as a whole, were referred to as
Caiber 83s.

.585 as stamped inside the casebake is equivalent to 14K gold.

IWC watches are manufactured in Schaffhausen, Switzerland

Sir, you're a gentleman and scholar. Thank you kindly for your patience and
help. Wish more boards were this smooth.
