GUB Automatic 23 Rubis, I can date the watch by the movement 67.1 dates between 1960-67 .It is 20 microns Gold plated case, a beautiful dial, even though it has some age,and spotting, I think it adds to its charm and character. You may notice the crown is not original and has been replaced quite recently (not by me).
Movement 67.1 the link is in German, it is the most comprehensive, that is I why I chose it, if you link it using Chrome browser it will translate it into the language you have set on your device/pc. If you are not using Chrome the link has a translator.
Here I have zoomed in on the back-case via cropping the picture, I will retake some close up pictures in macro, and update when I get the chance.
