Scratches/Dings on Daytona after service under warranty: Reply from Rolex

[NappaLover]

I just had my 116520 Daytona serviced at the RSC in Dallas under warranty, presumably due to a main spring failure. However, I am not certain of the latter since Rolex never tells customers what was actually broken when watches are serviced under warranty. The receipt also only states "complimentary movement service". I do treat my watches very well and the Daytona almost has no scratches, besides some hairline scratches on the clasp. This is why Rolex did not polish it after it was serviced.

In any case, when I received the watch back after 3.5 weeks, I noticed that the case back had some noticeable scratches (probably due to the tool used to remove the case back) and dings on both lugs in 5 and 11 o'clock (probably due to the bracelet being removed and/or reattached. See pics attached.

I don't think those damages are acceptable so I emailed Rolex USA. Only 5 days later (today), I received a reply from the RSC Dallas:
"I understand that you are dissatisfied with the service you received on your Daytona at our facility. I would like the opportunity to address your concerns. If you would like to drop off your watch, we can provide a complimentary touch up to address the scratches. We can also check the movement at any time in the next 5-7 years and provide a complimentary service if needed. If it is not convenient for you to stop by and drop off your watch, I would be happy to send packing materials so you can mail it to us and provide reimbursement for the postage. Please don’t hesitate to contact me if you have any questions or concerns."

My questions for you are as follows:

1. Do you think they handled this properly (I think so)?
2. I am not worried about them polishing the case back but do you think the lugs can be refinished/polished without removing too much metal? Or would this be too noticeable?
3. What do you think I should do moving forward?

Thanks guys!
