Help to identify my IWC cal.83

Good afternoon,

I started a thread in the New Forum, but I think this is a more suitable place

I recently inherited this IWC from my father: Cal. 83, movement number 1040718, case number 1087337,

I can’t find any information online about the model; I’ve only come across one identical to it but with a completely different logo and dial colour,

The dial, which I think is missing details such as the minute markers, doesn’t quite convince me, nor do the brand logo or the dial colour.

I think these details have faded over time, but what I am sure of is that the dial has never been restored. At most, a watchmaker might have cleaned it during a movement service, as the watch has always belonged to my family.

I would appreciate any clues on this matter so that I can find the best way to restore the dial.

Hello...was your father from the Uk?

Hello, no, he was not from UK, why?

N'worries..it may have explained how the dial become to be signed...the dial regardless of signature is certainly not regular fare for Zelim Jacot (Zj) the manafacturer.

What is the diameter of the case please..not including the crown?

35 mm

Have you any links to the other sample you found?

Yes, apparently, only the watch case is the same as mine

Thank you ^...

Bit of an odd one..i have not seen that case before from schaffhausen, it's got an air of custom about it..though they might have been testing the markets tastes ( other companies used that faceted-lug on a 35mm cushion cased offering in the same period)..

*prob..is scafusia is not a good look but no drama.

Thanks for showing it.

The watch belonged to my father’s only uncle; my father inherited it from him, and it has always been in the family.
My great-uncle was a businessman with interests in Europe in the 1940s. As far as I can recall, his wife told my father that it was a gift from a Swiss or Austrian businessman—
I can’t quite remember which—but it’s true that in those years they lived in Tangier, which was an extremely cosmopolitan city where you could find every imaginable luxury item of the time,perhaps he bought it there and it wasn’t actually a gift.
Perhaps, as you say, it’s a piece they used to gauge the market’s tastes.
