I have owned a few LE over the years and was quiet impressed with the Certina DS-3 1000m LE 1888 owners list You can See my LE 1351 could even add a picture. http://www.watchlinks.net/ds3swe.htm Not all are there but you can see a good amount of them in which country they are and even any stolen numbers that have been updated. This could be done with this release Maybe a feature @Robert-Jan might want to do on he's website. ( last thing I want is more work for you Robert ) What say all Just a idea
My comment was regarding a dedicated website, like the page you referenced to, showing name, surname, country and LE#. No rocket science to find me on insta, now you can edit your post. Thanks.
Best bet is to do it like a registry. With verification and blind contacts. The problem is adoption of the site. I'll give you an example. http://www.bmwmregistry.com/registry.php Then you add a blind email link through the registry server. But problem is there is no money in it. Of 68k e46ms about 1 out of 64 is listed.
