I sometimes wonder about how many collectible watches have made it into the hands of modern collectors, as compared with the estimated production of such. So as a first guesstimate here's a bit of data to consider. It is just for fun and it requires some assumptions (both explicit and not).

First, the watch(es) must be ones that more than a few collectors are interested in owning. Second, there must be a reasonable number believed to have been made and the runs for such be reasonably well defined (this is a very important point; widely scattered variants need not apply). Third, there must be a serious collector (one who knows where some of the bodies are buried, so to speak) who has a taken a long term (decades at least) interest in compiling data on them.

So below are a couple of examples to consider. If you have a favorite of your own, please post for discussion.

Aurora grade nos. 10-htg and 10-OF (data compiled by yours truly). ETP 420 and 300, respectively. Examples seen or reported are 53 and 48, respectively. So, 720 for both grades with 101 reported for a "known" percentage of 14.0%.

Another example that comes to mind are the early Hamilton mvts from 1 to 2000. Rhett Lucke has collected data on these and in a previous message board post reports having recorded 155 examples for a "known" percentage of 7.8%.

Thoughts?
