With all the mixed feedback on the Dallas service center I did specifically ask if it would (or could) go back to Switzerland vs Dallas. I was in no rush and happy to pay shipping but the boutique assured me the Dallas center does all the Duometres and they only need to ship the tourbillons and other complications back to la Maison. I think Dallas did a functional/good job of servicing but I would wager if it went back to Switzerland the movement would be spotless.
