Yep. They fixed my 1905 IWC and looked at my Oris. Great work at a more than fair rate. I believe his dad said he went through the rolex training at some point.
Only benefits are: Rolex parts and Rolex warranty?
I have read online that unless the shop is certified Rolex, they can not buy replacement parts directly from them. But for a cleaning and oiling I think they would be great.
