Hi, My dream was to start restoring an old OMEGA. I find an Old case 161.003 in a good state. The problem is that i'm not able to find the right caliber to put in it. I find only 2 watches with this case.One with an 550 caliber and another with 552 Caliber. So i am wondering if: --> I bought a fake (i loose 70 Euros, and i take a good lesson) --> there is an expert in this forum who can help me. The dial given with the case is a 29,50 mm diameter. And the case is a 34.10 mm diameter. Do you think an 269 caliber can be put in it? Greatings Morphelius
