Even for someone like myself it woukd be easier to have the parts listed on the invoice.
It’s rumoured that Omega change escapement parts when servicing co- axial movements, something that doesn’t happen routinely with a conventional movement unless it's very worn/old, but they weren't admitting to this because it was detrimental to the reputation of the co- axials.
I disagree with the practice of returning parts, they’re of no use to the owner, and the worry is that these parts get sold on. Omega replace hands when they don’t need replacing, so maybe they’re OK to buy used, but worn movement parts are usually no good. Crowns could get passed off as ‘ good condition’ when in truth the threads are worn, so someone ends up being ripped off if they buy them.
To me it makes more sense to list every part that’s been replaced on the invoice and forget about returning a bag of bits.
