Once you've seen that the movement performs normally, you can finish it with the rest.
Therfore rotate the movement and we'll start with the bits on top!
Not a lot of pics here as the process is quite straightforward. Anyway install in this order: "CANNON PINION WITH DRIVING WHEEL 028-A16", then together the "24HOUR WHEEL 103-A16" (103-A09 in the PDF) and the "MINUTE WHEEL AND PINION 072-998", and finally the other smaller gears: "INTERMEDIATE DATE CORRECTING WHEEL(1) 087-A71", "INTERMEDIATE DATE CORRECTING WHEEL(2) 087-A75", "CALENDAR CORRECTOR WHEEL 213-614" and the "INTERMEDIATE DATE CORRECTING WHEEL 087-A72":
It's now the time for the 2 springs (named respectively "Date jumper 109-875" - 109-870 in the PDF; and teh "CALENDAR CORRECTOR LEVER SPRING 903-A17"), one acting on the date wheel and one for the "INTERMEDIATE DATE CORRECTING WHEEL 087-A72", plus you put the "Hour wheel 075-A51" with its copper washer and finally also the date wheel/disk:
Note: if you don't manage to make the "Date jumper 109-875" - 109-870 in the PDF - to stay in place, you can fix it later: there's a small hole in the top plate to fix it.
Finally the top plate "DATE INDICATOR MAINTAINING PLATE / HOUR WHEEL SPRING 176-A04" with its 5 tiny screws:
Test that the stem works fine, that you can manually wind the movement, set the time and quick change the date. Test also that the date changes automatically moving the time forward in the time setting position. If all is fine, regulate the movement, and as very lastly put back the autowind rotor and you've done!
Here the results after the service (remember it was running with 166° amplitude before...):

I may say that I'm pretty satisfied of the results, also because I've never seen a 9015 going up to more than 300° of amplitude!
I think that the initial problem was simply that the main barrel got opened: it is visible by how the main spring was not plain in the open barrel picture, plus when I disassembled the movement I found it open...
