My first Universal Geneve watch

Yesterday at the local flea market I bought a manual wind gold plated Universal Geneve for 80 euros:



The numbers of the caseback are 1237303, 40601 so this watch is from 1945-6 according to the serial numbers table. The movement is Universal geneve 265.
What do you think about this watch; Did I make a good buy; Also I am curius about the fact tha the movement has the number 158877 engraved, which is curius because from what I have read so far, Universal Geneve put the serial number of the watches on the caseback and not in the movement. Do you know what this number is;

I wish I could find anything even remotely close to this in my local markets. Nice find!
