    who produced smallest automatic movement?

    Hi,

    I have one old(er) Roamer woman watch (my grandmothers watch) that uses automatic movement.Movement has date feature and it's over 30 years old.It was serviced few days ago but I forgot to photograph the movement at my watchmen :oops:
    I was wondering who produced smallest automatic movement with date in history?
    I found this one http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&ETA_2365
    but it does not have date
    I think that the movement in my grandmothers watch could be ETA 2369 ( http://www.ranfft.de/cgi-bin/bidfun-...2uswk&ETA_2369 )

    :thanks

    The smallest ones shows in Bestfit are 6.75''' (there's one by Eterna, the 1419 "Golden Heart", and one by Mido, the 0617p). I'm assuming they're different movments, 'cause they don't seem to share any parts.

    If you search for Dr Ranfft's posts, he posted about this a month or two ago.

    I think he said Eterna produced the first women's automatic movement and also produced the smallest automatic.

    I think JLC holds the record for smallest manual wind

    photos here of a neat little auto date water resistant old Seiko. Smallest of many autowinds I have seen.

    Well, the smallest automatic movement is probably the Omega 660 series - certainly if you base it on combination of diameter and height:

    http://www.ranfft.de/cgi-bin/bidfun-...uswk&Omega_660

    ...which is only 15mm or about 6.5''' across. However, that doesn't have a date. As for the ones with date, there are probably several candidates, including the Omega 680 series (at 17.5mm or about 7.5'''). My mother has that one in a Seamaster Cosmic.

    So I get the idea to search for "smallest" on Ranfft and what do I find?

    1967-
    smallest ever industrial manufactured automatic movement, regarding the diameter
    The only competitor is the Omega 660, with a 2.6% smaller volume, but a 14% bigger diameter.
