: I would like to add one point:

: 4) Discovery and research
: Almost every week this very forum shows a new discovery which
: immediately gets thoroughly discussed. Even a long-time
: collector may be surprised, let alone a Heuer greenhorn like me.

: In a former life I collected vintage IWC watches until it got more
: and more boring. In the vintage Heuer area there are more
: exciting opportunities on both sides of the thin line between
: rare, previously unseen piece and put-together horror.

It's what keeps it interesting even for the collectors who have been in it for years now, and some brands are documented much more completely, leaving little scope for research. I have delved deep in Heuer lore and still do, and there are still things out there I know nothing about. And that's a good thing!
