    Pocket watches movement identification help.

    Hi all,

    Please help me to identify the 2 movements, Doxa and Longines.

    Need to change both balance staffs but the Ronda catalogue is of no help without the Cal. number.

    Thanks in advance and happy passover and Easter ,

    Saul.

    Possibly a Longines 18.80. See:

    "Doxa" is FHF H4 or H5.Check Ranffts pink pages If you want to be sure.

    I have checked it on RANFFTS and the dial is different but the train side is pritty much the same. Can I assume that in terms of balance staff they are the same?

    After a tedious serch it seems that the Longines is Cal. 19.75
    I would love to hear your comments.
    On the Ronda catalogue, there are 2 staffs for this caliber, one with pivot 11 (Ronda 234) and the second is pivot 13 (Ronda 1613). On the original broken staff both pivots are gone. any suggestions?

    Thanks,
    Saul.

    I can find no reference to these different pivot types in my literature, I notice that
    there is a difference of 4/100ths mm difference in length of staff.
    My suggestion would be to fit up a piece of pivot steel between the
    endstones allowing for end shake and obtain the length that way.
    Or you could buy one and if you are unlucky then buy the other.
