I recently returned an 18 month old Sd43 for regulation under warranty - running up to 30 secs/day slow. The watch came from an AD in Liverpool, I live in Reading so took it into Goldsmiths who charged me £30 for the privilege of sending it to Rolex (because it wasn't sourced from them originally). The last time I sent a watch into Rolex under similar conditions was around 5 years ago and there was no charge (that one was bought in the States) - is this now standard practice from AD's who don't sell the watch originally?
It came back within a month running spot on btw.
