Hi All - new member joining to the forum.
I have 2 units of the movement, AM0184 and AM0187 - both are working more consistently than any of my Seiko 7s26/NH35 - however, I am surprised with this cause I have fully disassembled, cleaned and oiled them both and I have a negative impression of what I have observed.
They are not a quality built - that includes very soft materials, excessive assembly tolerances, poor design features, inadequate/non-existent oiling,dirty assembly environment and poor/dirty assembly practices (fingerprints and dirt all over the parts).
I can give you more explainations if any of you have any wonder. Just ask.
