This is what I currently know about the watch
Omega Constellation Electronic
Chronometer f300Hz, calibre 1250, movement no. 34,793,216, approximately 1972.

I’m very aware that the back is not original and that the battery is Japanese because I bought the watch from Japan. I’m trying to find the exact reference number yet. I’m struggling very much. ChatGPT is no help. when I purchased it, It did come with no reference number and apparently usually it’s on the case back but of course Mines unoriginal so there’s no help there. anyone can help that would be really nice Nice thank you very much!

(These photos are from the seller that I bought watch from. I’ve only used them because they were more professional and clearer than ones I can take)
