There is category of watches who are closely associated with to either famous people or notable events. Examples that come to mind include:
1) Tudor - Tiger (Woods)
2) Maurice Lacroix - Roger Federer
3) Omega Speedmaster Pro - Moon
Here's the question - if the object to which the name of the watch is linked falls out of grace - what happens to watch values?
Take for example recent scandals surrounding Tiger Woods. Did Tiger's missteps make the Tudor Tiger watch less desirable / loved for you?
Alternatively, there are theories that US Astronauts never landed on Moon and entire event was staged in some studio on Earth. Pretend that one day one of those theories will be accepted and we discover that Omega Speedy was never worn on Moon. Will you love your Speedy Moon less?
