Super,
Toni,
thanks very much!

: Jeff contacted me with regard to this question
: and here is my comment, based on some
: research I have done and a little Heuer
: knowledge.

: The plate on the left looks like a genuine
: Heuer item; however - the quality of the
: milling seems a little poor although it
: appears to have been done by hand as the
: originals were, i.e. not automatically
: machined otherwise it would have a series of
: 25mm diameter 'swirls' inside the main cut
: out. Its tough to tell exactly with the
: picture at this oblique angle.

: In addition the countersunk holes are quite
: roughly cut on the left, possibly indicating
: that a not so skillful craftsman made this.
: Alternatively it may just have been
: rechromed and it is notoriouly difficult to
: polish up 'as new', particularly in smallcut
: outs. Having said that the cut out for the
: crown is very square, indicating that its
: not a heuer original.

: lastly the thickness of the plate is not quite
: as the originals I suspect (the one on the
: right is the real thing) and I think that
: this is possibly made from a metric plate
: size, again pointing to it not being a heuer
: item.

: my judgement would be that this is a either a
: very very tatty original, made good, or a
: copy for another manufacturer or private
: source.

: Also check the back for the usual lettering,
: either die stamped or finely engraved at
: about what would be about 1mm high letters.

: The plate on the right by comparision looks
: like the earlier thicker type (probably
: stamped ED Heuer & Co on the back ?) and
: you can see straight away the fine quality
: of the milling and depth of profectus /
: chrome finish. Tis one just looks right.

: Hope this is useful.

: Regards

: Tony
