Well if Josh is preservicing the rolex eta's, I cant see why he wouldnt expand his service eventually to the 7750 models. I dont mind the cost of getting it serviced, but I absolutely dread the hassle of getting a watch I am all excited about and then having to ship it right out for servicing with the risks associated with shipping (i.e., lost in mail, dmaged in mail, or customs). I know the shipping risks are rare when just sending it out for servicing, but it is still a concern. Plus, when I get that new watch, I just love to wear it...not send it out.
Edit: @squeaker, you can also read alot about the 7750 on THIS THREAD
