My Grandfother's Watch Investigation Room

I want to ivestigate and find out of what and where my Grandfather's
Amazing Golden Pocket Watch Originated from. ‍ ‍ ‍ ‍

First of all, what is the reason I couldn't find any exact same watch on the internet, I need some experts to help.

The watch had been purchased by my Grandfather either in 1948 in the Czech Republic or in 19 perfect condition without polish, in either the Czech Republic or the USA in 1963.
The watch had been taken to a few watch experts who deal with patek philippe and hublot, who were absolutely blown away by the watch, they confirmed its gold and its original but did not give info because my mother hadn't asked them more about it.

We do not intend to sell it but rather to keep it and fnid out more about it.
Here's a photo of the watch.

Unfortunately I am not blown away by your watch.
It is a classic example of a so called marriage.
In those days IWC never has made a wrist watch with small second at 9 o'clock. Probably it is a small ladies pocket watch converted into a wrist watch.
If we could see the movement and its number we could better identify it.

well, unfortunately I couldn't find any number on it.
I also have his old seamaster 120 and 300...
I was really hoping for something special there.
Is that still necessary to cover it on my insurance plan?
What is the price you'd say it's worth?
the watch is in its original form and working, I do need to say tho,
does the fact that it has a 60 second dial on the left and only on the left mean something?
Is this unusual?
Is this the reason I didn't find any perfect fitting photos matching it on the internet?
If you wish to see its dial movement movement in wish you'll find out more about it I could send you an email with a video of it in action.
The watch is not automatic as you may know.
Thank you for everything, best regards - Daniel.

Hi Daniel,
A few answers,
If the second subdial is at 9 o'clock, in most cases it means that the watch was originaly a pocket watch.
A pocket watch has its crown ( unless it is a hunter) at 12 o'clock and its small second at 6 o'clock. By turning the whole watch clockwise over 45 degrees, the crown is now at 3 o'clock as it is usual in a wrist watch. But inevitably the subdial has moved to the nine o'clock position. Before 1990, IWC never made a wristwatch with a subdial at 9 o'clock. The first after 1990 were Ref. 5251 (moonphase wristwatch) and the first Portugieser Minute Repeater.
Your watch is much older and from a period that IWC only made wristwatches with a subdial at 6 o'clock.
It is very unlikely that an IWC movement has no movement number.

For the real collector such watch has no value.
I would not bother about insurance.

Can you post an image of the movement along with details of any numbering/markings on it, and do the same for the inside case back.

If you do not know how to open the case PLEASE get a watchmaker to do it for you, then photograph/record the details as above.

If you cannot upload the images, email them to me at the link below and I'll host them.

Cheers from the cellar
