The pack the part is in is oxygen free so it stops or rather slows down oxidation of the lubricant on the part. It is already a 'dry' lubricant, so is unlikely to dissipate like greases and oils. If the lubricant on the reversing wheel(s) has gone over time, you'll soon know when winding the watch and seeing the rotor spin as well. if that is the case, remove the reversing wheel, clean and lubricate. No biggie!

100 % yes! As seen in this post, I gave up the idea of polishing using a rotary tool and got myself a proper polishing machine. Achieving extremely shiny surfaces without the slightest trace of scratches is very difficult but fortunately the scratches are invisible to the naked eye and only visible under high magnification (10X or more). I am very happy with the level I have reached. I will try to write a bit more in detail about the techniques I use but I don't have time right now. I will return with a link in this thread when I have done so. Here you can see examples of what I recently achieved with my polishing technique.

oh thanks for this! I also noticed that Cousins would mention the compatibility between ETA and Selitta for some parts, but not for others (incl reversing wheels), see two sceenshots below: Yes, my instinct here is the same. Either clean+V105 or use as-is from the blister.

There are two good cross-references you can check, and I already did. https://www.emmywatch.com/db http://cgi.julesborel.com/?_gl=1*1c1sjug*_gcl_au*OTE2ODU1MjI1LjE3MTc2NzkyMzM. None of these cross-references shows that the ETA and Sellita calibres are interchangeable in this respect. I'm not sure though as it could be that the databases haven't been updated. I would not apply V105 w/o first properly cleaning them.

Thanks! I must indeed have stumbled on an older version (two actually) and neither of them mentioned this oiling point. But it seemed to make sense and great that I can now see the latest doc to confirm. Yes, they are pre-lubricated. But how old is this lubrication if it's still original ETA parts?? Could be 10-year-old stock that Cousins is still selling... I'm worried that the pre-lubrication has dried out. That being said, it seems to work fine (no spinning) --- for now. Not sure if it'll wear out quickly, though (if the pre-lubrication wasn't good anymore).
