also has 109 on the back cover along with IWC logo

Welcome to the Forum,

I assume that "1219583" is the case number and using Date your IWC the case was produced in 1950 of after. If you have the movement number the above program will identify the production date and the calibre of the movement.

The "109" is probably inside the mark of a hammer head and using Solving the case, the case was made by Oreade, Manufacture de boites SA.

Looking forward to seeing your images.

WELL I SENT THEM TO YOUR MAIL HAVE NO IDEA HOW TO GET THEM ON HERE YET THANKS!!
P.S WATCH DOES RUN BEAUTIFULLY

The dial

Close up

Inside case back

you can see the "109" in the hammer head mentioned earlier

Using Date you IWC the calibre 89 movement was produced in 1949 and the case most likely in 1951.

I suspect the watch is a Ref 383 and the measurements will tell. The reference number is not related to the dial but the case dimensions and style, the type of lugs and the movement.

After all these years a service by a competent watch maker would be good for the movement. Personally I'd remove the bracelet and add a nice tan/brown strap.

Nice watch to keep in the family.

Thanks for your profesionalism! The speed at which you handled it was awesome (not used to that) What a great site!
