    Comparison of selected 11.5''' movements for interchangeability update (v3 May 2011)

    File updated to v3. It now includes the ETA 2834-2 and 2836-2. (May 2011)
    --------------------------------------------------------------------------------------

    I am starting this third thread for the same topic discussed a few months ago for easy reference. Thinking of a watch project I struggled to understand the technical details for the various commonly used Chinese and Swiss movements.

    With the help and encouragement of the Chinese Mechanical watches forum users I have now finished compiling a tech spec sheet for easy reference.

    Please let me know should you spot any erroneous info and I am happy to change and upload a new pdf file. Latest version as of February 18, 2011 is v2.

    (To allow for keyword searching within WUS and the WWW here the main concepts of the pdf file: movement diameter, movement height, stem height, hand size, dial feet position, beat frequency, Miyota, Hangzhou, Nanning, Dixmont Guangzhou, Seagull, Shanghai watch factory, ETA)

    Thanks for adding to the library gifgy!

    This is the first document that I have seen that states the ETA 2836 hands are different sizes than the ETA 2824...can anyone confirm is this is correct?

    I think that may be a typo since most of the parts are the same for the 2824 and the 2836.

    Although stem height of 2824 (1.8mm) and 2892 (1.5mm) are different, ETA 2824's reference dial design is domed, and 2892 one is flat. So whether you can fit a 2892 on a 2824 case very much depends on the dial design.

    Same for the ST18 (2892 clone) and ST21 (2824 clone). It is not easy to determine changeability simply based on stem height.
