: Thanks Mark, much appreciated. I agree the Heuer logo must of been
: added afterwards. Is this a watch posted in a thread, I have
: looked throughout this site and have not seen it. Have you ever
: seen early Heuer's marked E.HEUER & Co where the
: "o" is in the "C", I usually see them marked
: ED.HEUER or HEUER. My intention is to get the watch fully
: refurbished including the dial (as is no logo) as I want to
: mount it on a period strap and enjoy it. I know removing the
: patina would actually devalue the watch somewhat however I feel
: I would enjoy it more that way. I need to find someone to do
: this, I know where to get the dial redone, case needs to be
: reworked and re-silvered and interior workings re-built. The
: good news is the watch runs.
