Thanks Stewart, much appreciated. I was referring to the Le Jour version when I was asking about Heuer manufacture. Do you have any information that confirms the Le Jour was made by Heuer? The subdials on the Le Jour don't seem to be recessed as they are on the Heuer version (unless it only appears that way in the photos I've seen) but that may have been Heuer manufacturing the Le Jour to a lower price point. Thanks again for any additional info you can provide.
