It's a LeJour, right?
The go-to place to start will be to simply type "Vintage LeJour Chronograph" in Google and then work through the pages suggested until you find one or two that matches and start reading. That will typically give you a reference number that you can use to narrow down the research with.
Take anything written on a dealer's webpage with a healthy dose of scepticism 😀
I am certain the papers you have will give you as much or more information than we would be able to, especially considering your avatar is the only picture you are giving us.
You will need to post larger and better pictures of the watch in question. You can click on options on your post and you will see add photos. If you are using your computer and you have photos of the watch in your computer, simply click on "add photos" and you will be able to select the photos you wish to add to your post. Hold down the shift key if you want to select more than one photo. You can also use your phone, when you click on "add photos" it will bring up a selection, select "phone library" and select the photos you wish to add.
Or provide the information on the papers you have on the watch in question... you can take a picture of the papers too.
I hate to see anyone lose money so I will gladly pay you what it cost you. That's the kinda guy I am! 😁
Seriously though I think you might find something similar online that was recently sold on Ebay, or as mentioned a dealer might be listing one but the price might be highly inflated.
Hi all, I am not a watch expert at all and I am asking any of you who have info on this watch that I bought almost 50 years ago. I have worn it about 10 times over the years and it was always put back in its box. My avatar shows a picture of the watch. It is in perfect condition with all the papers and the two boxes it was sold in.
I think the retail slip says $88.20... really think you should make it an even $100.00 taking inflation into account. Hope Lost will be able to determine what it's worth. The condition seems mint with all the goodies.
What do you think I'm made of money?
I believe its movement is a Valjoux 72, as used in Heuers and Rolexes at the same time (and many other decent makes). So, yes, its a quality movement. 1974? A little late for a Valjoux 72, so it might have been on the jewellers shelf for a while, not that that is necessarily bad. Plenty of spares around and watchmakers who understand Valjoux, so no problems with servicing. However, please do not wind and run it now, the lubricants will have dried up after ~45 years.
You will have no problem selling it, lots of good pictures in the right places, here, Chronocentric and so on. AND I'll give you twice J&F's offer as a "Sell it Now" instant deal. More seriously, wait and hang on for the 100th offer, do not take the first. Or get it serviced and wear it a lot.
Very nice piece, can you tell us where you got the plans for your time machine?
Found one that was for sale for 2200.00 without bracelet.

Hope this gives you an idea, considering you have B and P, the condition of the watch and it comes with a bracelet... 2,800 to 3,500? I couldn't find a listing on eBay, but, you can call a vintage dealer or search the internet. It's an attractive timepiece... no question.
