IWC Ingenieur Jumbo 3003; ant inputs?

Hi
All

I'm looking for quite some time at the IWC Ingenieur Jumbo from Gerald Genta
(1832 & 3003).
i saw one of the 3003 online (if I'm not mistaken, the Quartz model is rarer
then the automatic one).
What is confusing me, is that on the original paper the refence 3003 is
mentioned, but on the inside of the caseback 1832 is mentioned. I know that
some automatic models were changed to quartz or viceversa.
But the original papers is mentioning 3003, hence the 1832 on the caseback is
confusing me. Happy for any inputs on this topic!

As well I was wondering what a fair price for such a watch would be. The
automatic 1832 has prices between 15-20k on Chrono. What do you think would be
a fair price for a 3003 in the conditions as in the pictures?

thx a lot for the inputs!

This is not an uncommon configuration.

And there are several reasons why:

- The customers ordered a watch with a mechanical movement and then wanted a
"modern" watch with a quartz movement, because both variants were offered.

- Watches that have already been purchased have been converted on customer's
request.

- IWC still offers a conversion to automatic for 1832 with quartz movements,
but not vice versa, because there are no quartz movements availabbe anymore.

Conclusion: A 3003 with the option to be converted to a 1832, what has become
quite expensive, but compared to the current price it could be a good deal ?!

Thx for the input.
In that case it means that an 1832 was changed to a 'modern' 3003. Hence, the
caseback still mentions 1832 but on the papers 3003 is mentioned.
A couple of questions remain from my side;

1) I was not able to find prices for 3003 versions online. Was wondering what
would be a reasonable range.
2) If I would ask IWC to change the 3003 back to a 1832;

-how much would that apprximately cost?

-will they use an original movement from the 70s or something new?
-regarding the dial; same question. Do they still have tritium dials from the 70s for this watch?
-> if I would decide to do that, I want to avoid ending up with a Frankenstein watch.

Well, the conversion will be carried out by IWC and confirmed with an extract
from the ledger.

- An authentic cal. 8541 will be used for the conversion and of course a NEW
SL ZB and SL Hands.

- The papers are 3003, but the case is an 1832, which is also not a problem
and can be found frequently.

Ref. 1832 will then appear in the extract from the ledger, making it
officially an authentic 1832.
