I called the Dallas Rolex service center and was told that they will not service any Rolex that is not in its original 'born' state. Seems like a rather strict policy. But if true, it would seem to support what the AD's contention that this was a custom order. It has been serviced by Rolex twice.
The lady also told me that they do not keep any records there, or anywhere else, to verify authenticity. They will provide an insurance value upon examintation of the watch. She stated that they will only do this for watches in their original state.
