    I got a hold of a Longines p/w with a broken balance staff. All I have is a serial number and what looks like 1971 and the word swiss on the pillar plate. It's a 15j,D.R., 43mm plate size. Where would I get a part number for the staff; or if anyone has a part number, would appreciate it, thanks.

    Foghorn,

    Check out this Longines site, shown to this list by Tony "Nachtmotte", which lists many Longines calibers including the 19.71 to help ID your movement, as well as for other Longines information.

    IMHO, I think we're on the right track. At least I know in what year the movement was made; so far, so good.
    By the way, that rooster, Col. Foghorn was no relation to me.:)

    I have a quality pocket watch (18 ligne) in a gold hunter case. The
    movement is fully jeweled with a Breguet (overcoil) hairspring and a
    micro adjustable regulator. The plates are brass coloured and the
    balance has regulating screws all round it. It is a lever movement. I
    think it must be of high quality because of the Breguet hairspring,
    these were not used in `run of the mill` watches. There is no make on
    the dial with its black arabic figures on a white dial with a
    subsiduary seconds dial at 6 o'clock. The only mark on the plates
    (that I can see) is a shield with the initials H & H over a capital
    D. I was in the watch trade back in the 1950s and 1960s and am very
    conversant with most makers of that and earlier era but this has
    defeated me. Inside the case back there is a logo that looks like a
    crown inside a circle and the gold mark of 0.585. The watch has come
    to light in Eastern Europe in the last couple of years but I would
    love to know who made it . Hopefully there is somebody out there that
    is very knowledgeable and can help me. Thank you.

    jolox,

    Your watch is potentially from Hahmacher & Hahn, Dortmund (Germany), who according to Kochmann in "Clock & Watch Trademark Index of European Origin" lists H&H / D in a shield as their trademark.

    Good Day Leghorn,

    I may be able to help with the staff You need but first we must establish exactly which one You do need for your movement.

    Namely there are several models of Cal 19.71. The 19.71A, 19.71N, 19.71NI, 19.71NF and there are variations of the pivot sizes like 11, 11 1/2 and pivot size 13 (and these are not all derivations of cal 19.71).

    We are talking of several different balance staffs here.

    19.71 Lohner 588 50 - Ronda 1613
    19.71A Lohner 588 50 - Ronda 1613

    19.71 Lohner 588 50/A - Ronda 234
    19.71A Lohner 588 50/A - Ronda 234

    19.71N Lohner 588 47/A - Ronda 917
    19.71NI Lohner 588 47/A - Ronda 917
    19.71NF Lohner 588 47/A - Ronda 917

    BS length/bottom length/bw seat/rlr seat/spring seat/pivot

    L 588 50 - 546 263 136 54 91 P13
    L 588 50/A - 541 258 135 64 90 P11
    L 588 47/A - 515 258 130 64 91

    R917 - 515 258 130 64 90 P11
    R1612 - 515 258 135 64 90

    R920 - 518 260 135 65 90
    R1609 - 518 260 135 63 90 P11 1/2

    R234 - 541 258 135 64 90 P11
    R1613 - 545 264 135 65 90 P13

    From the above it is quite obvious that You must establish exact movement that You have and then again You have to find out what size pivots You need.

    There are some Bestfit staffs that may fit as well like:

    Bestfit# BS length/bottom length/bw seat/rlr seat/spring seat/pivot

    100/515 - 513 258 135 64 90
    100/518 - 541 258 135 64 90
    100/520 - 545 264 135 65 92
    100/591 - 515 262 138 63 90

    I can help only with some of the above as I do not have all the variations. I cannot say offhand what I have in stock for sure apart from Ronda 917 and Ronda 1613.

    Anyhow after You find what exactly You need there should be no problem in finding yourself a new balance staff, I am sure that there are many other staffs of similar sizes that can be made to fit easily.

    Cheers

    Dushan

    Good day Dushan

    As soon as I can, I will pull the staff out and take some measurements. Hopefully, I will match one of a set of numbers that you have shown on your list, and come up with a number for the balance staff. And , if I am still in luck,you will have that number in your stock. I will let you know how I make out.

    Thanks for the reply.
