When you look at listings for watches (both new and used) you see the term "rare" or "very rare" used a lot. But I think of rare as more associated with stamps and coins. A small mistake in printing a set of stamps, or gold coins found on a 17th century shipwreck are perhaps rare.
Most watch manufacturers can't wait to turn out a run of Limited Edition watches with a production range of just a few to thousands. But does that make them Rare or just Limited Editions. In your opinion can something new be rare or does it need to be older to be considered rare?
What watches do you think are defined as rare?
