I am a bit surprised your Duometre was not sent back to JLC in Switzerland as I have spoken to a couple JLC boutiques which confirmed that the watch had to return to the manufacturer...
as the Duometre movements are serviced in their "haute horlogerie" department which is their high-end department that handles grand complication pieces and more difficult and delicate movements.
In fact, when I had my platinum Duometre Chronograph serviced in 2017, it was done so at the JLC manufacturer in Switzerland.
