    Hi everybody,

    My old-schooled father picked up a vintage IWC from an antique shop as a gift
    for me. I def appreciate his thoughts but still, I want to see if he got a
    fair deal on the watch. It says it's cal.171 and ref.1220.

    Hope that you can shed some light on this one! Thank you so much and hope you
    have a good day!

    You have received a lovely IWC watch. From a very thoughtful father.

    Enjoy it and wear it in good health.

    This Forum does not allow links to for-sale sites so I cannot comment on the
    comparison.

    thank you for the reply first!

    Sorry I was not aware of this, I just thought it might be helpful. It was just
    the same I found on the internet. I have taken it down. Hope it's ok?

    Thank You

    If you have specific questions regarding age etc - if you supply the serial
    number, we will be happy to date it for you.

    We do not generally discuss values of watches.

    Dear Carmen and Alexander

    the IWC Cal. 171 is one of the movements not designed by IWC itself, but
    bought in from other makers. Especially ultra slim IWC ladies watches from the
    late 1960s, 1970s and 1980s have such movements in it. The IWC Cal. 171 is in
    the very end a Frederic Piguet Cal. 21, 9''' in diameter, 1.75mm in height.
    Patek and other well known brands have used it for slim ladies watches as
    well. It was regularly sold in gold cases.

    Other than the IWC movements which are basically an ETA movement IWC
    movements deriving from Frederic Piguet or Jaeger LeCoultre movements are
    Haute Horlogerie. Unfortunately only few collectors collect ladies watches. So
    the price depends on the look: They are bought to wear them, not bought as
    collectors items.

    My wife wears a ladies Ingenieur, having as well a Piguet movement, but an
    automatic and more sturdy one than the Piguet 171.

    Regards

    Th. Koenig

    Thomas, amazed to get to know what I did not know. There is my answer to my
    question - what were those "ultra thin's".

    Thanks for sharing the knowledge.

    @ Mark

    At the same time, I was looking for details in old Watch magazines. Here are
    some scans.

    Perhaps it helps a little bit ?!

    Hebe, thanks for this. I had no idea of the use of that Piquet movement!
