I know its kind of late to reply to this thread but I did find a Rep friendly watch smith in Dubai/Sharjah.
So I bought this Rolex Sub-C and wanted to remove extra links from the chain.
So I took it to a shop called MINUTES in Sahara Center on Dubai/ Sharjah Highway, where I gave him the watch to remove the links.
The Watch smith asked me if this was genuine or Rep. and I honestly told him that it was a Rep.
Anyways, he removed 2 links and charged me Dhs. 10 for it.
So out of curiosity I did ask him if they did do watch servicing as well, and they said YES. Just to confirm I asked him if they did servicing for these type of reps and he agreed that they have done it before for both genuine as well as rep watches.
last question to him was how much normally they charged for the servicing and the reply was Dhs. 100-120
I have not tested there servicing but they did seem to know what they were talking about. So when the time does come for servicing, will definitely be taking my watch to them.
Hope it helps fellow Rep enthusiasts in Dubai/Sharjah
