I have dealt with this site before but only to buy a Panerai case and they were very good indeed.
This is not an endorsement though as I would still stick with our forum dealers - Especially Josh who has never let me down yet.
1. HKtan for sure...The quality is right up there and he can make OEM specs.
2. Ar will peel or rub off of these watches...No brainer here - Go with Chief.
3. The Zigmeister or Vac.
4. Maybe Ebay but not really needed.
5. Contact Vac as he may be offering this service.
6. Maybe making the rotor a little quieter.
Actually there was a recent article which I am trying to find from IWC stating that they are selling more watches than normal and that they are in fantastic shape. Not sure if that goes for all luxury watch makers but at least one is still doing well or better than expected.
I'm just saying that gen dials do not have bits of glue or crooked markers on them.
At the end of the day it's your decision.
P.S Maybe a Loupe would have been helpful in this instance before you committed to buying this.
