I'm sorry that I pointed it out. I think that my PO wasn't assembled properly. The hour hand nearly touched the dial at the 6 o'clock position. It only didn't touch the omega logo because the dial was also installed unevenly. To solve the problem I reinstalled the dial with an H4 cannon pinion. And now I'm a bit concerned that the distance is too big. By the way, don't forget to secure the he valve with loctite. The rep ones are not easy to get anymore and the gen valve is quite expensive.
