    Hi! I recently bought a vintage IWC cal 852 from a vintage watch store.

    The watch has been polished, and according to the dealer, the crown and the
    strap have been replaced, otherwise all parts are original.

    I would like to know the authenticity of this watch, and whether the dealer's
    statement is true.

    Thanks!

    From the photos you included, it appears to be authentic. The only way to be
    certain is to send it to IWC in Switzerland where, for a fee, they will
    provide an excerpt from their archives.

    I will say the signature on the dial looks a bit sloppy, suggesting that the
    dial has been refinished. But sometimes the constant polishing of an acrylic
    crystal will make what is seen through it appear distorted.

    Very classic, handsome watch you have, by the way. Congratulations.

    Hi Yjuso,

    everything looks fine, but from what i see the dial is redone. Check the
    minute markers on the circumfence they look somehow suspicious.

    Also for an IWC from the 50ties the dial looks to good to be true.

    very nice watch anyhow.

    Thank you for the good advice! I believe the signature came out a little
    sloppy in the photo because of the resolution, but I will check on that.

    The history of Cal. 852 is one to remember.

    It was the first calibre in which Albert Pellaton built his famous Pellaton
    automatic winding system. This calibre was used in the first vintage
    Ingenieurs.

    In the decade following, cal. 852 was improved many times : cal. 8521( with
    date), cal.853, 8531, 8541, 8541B.

    These calibres were hall marked by the independant press as among the best
    automatic movements ever made in Switzerland.

    Hi vintage Forumers,

    to shine a light on the first automatic movements constructed by Albert
    Pellaton in Schaffhausen.

    From juergen Kings article in Watch 3/2001 i took the following snip:

    It all started with Cal. 81 in 1950 that was an automatic movement with a
    small second hand at 6 o clock position. Only 1800 movements of Cal. 81 where
    produced, and even Jurgen King wasn't in possession any picture of a Cal. 81
    movement or complete watch. In the Watch 3/2001 he asked the reders of the IWC
    publication if anybody would have such a watch or an image of it.

    Still in 19501 the Cal. 85 was introduced which is a center second automatic
    movement. There are rumours that all remaining Cal 81 movements where "modded"
    into center Second cal. 85 movements. 8400 movements of calibre 85 where
    produced.

    In 1951 the Cal.852 was introduced as a successor to the Cal85. That means the
    Pellaton Automatic design has quickly evolved into the Cal 852 of which 50400
    movements have been produced up until 1959
