GMT II Bezel Change -

Hi to all the members here. I am relatively new to this forum but not new to Rolex. I currently own a Z series 16710(coke), Z series 116713LN, K series 16610, T series 16220. My wife a D series 178271 and a T series 79174.

I have a question that maybe some of you can help me out with.

I brought my Z series 16710 over to Rolex Hong Kong for servicing today, to get a replacement crystal(large scratch and chips), case buffing and and early servicing. Purchased the watch in Sept 2006.

It came with the Red and Black bezel. I inquired to the service lady about changing the bezel to the all black. She said they would not do it because the serial number indicates that this is a Red/Black combo and not the all black, therefore they could not do it because the watch would now be a different part number. She told me my watch was a part number 16710 T ST.....

I know many of you that have a 16710 have changed to an all black bezel.
My question is was this done at a Rolex service center or an AD? Where did you purchase your bezel, and I only want original Rolex parts... I know there are aftermarkets on fleabay......not interested in that.

Any help would be appreciated...PM me if need be.

Great forum BTW
Thanks
