    Question Sinn 144 GMT Repair question

    Greetings.
    I have a 144 GMT that had become increasingly hard to wind. It has finally stopped and does not run.
    The question I have is should I bring it to a capable watchmaker here in the states of send it home to its birthplace Germany.


    Thanks!!

    it has a 7750 in it and no special gas or oil, so RGM could easily service it, or a competent watchmaker as well.

    Thanks for the quick reply.
    It does have the Ar moisture wick in it.
    This is the high end "Katun" model with the display back and Titanium case and band.
    I was told it does have some sort of inert gas; but I could have been misled. I am the original owner.

    Update: According to an appraisal I just found, it has the Valjoux 7752, 25 jewel movement, is Argon gas filled and has the dry capsule technology. The case and bracelet are made of pure Titanium. It is the 144.GMT.Ti
    Also has the second hour hand for two time zones.


    I'm guessing its off to Germany.

    RGM now has a gas filling machine, so they are a local option.
