Vintage Omega Chronomat

Hello:
Maybe someone can shed some light on my issue. I bought this watch around 1974 at a Navy PX. I have been unable to find much information on it on the internet and most jeweler are clueless regarding its value. The Omega store in town told me yesterday that it is one of the first chronomts made and probably for the military, and suggested I post here for some additional information. Any help would be appreciated. Thank you in advance.

I did not think it was a possibility, but your photography skills are worse than mine. Try to take and post some better pictures. Also have the dealer open the case back and take a picture of the inner caseback. You can then search online with the reference number.

Agreed about the photography. Obviously not my strength 😉

Thank you very much. This was very enlightening. I had a jeweler offer me 200 dollars for it. I knew that was silly but I had no frame of reference to its actual value. Appreciate this information
