Unless you're saying the entire watch collectors market is a scam driven by companies and not collectors.
Do you think Action Comics #1 would drop in value if DC reprinted it? No. It's worth $3 million because the collectors care about the history that represents and the rarity of finding the original. Otherwise it's just ink on shitty paper. Collectors are deciding the value of the original and it can't be manipulated by merely making a new version. Omega would have to start selling the real thing for less money to tank the price. A clone can't do that.
People aren't going to stop buying the original either. Think about knock off designer handbags. It's easy to get a really high quality fake. But no one is buying the fakes if they can have the real thing. A watch collector sure isn't buying the fake since the movement would play a big part in owning that specific model. You want the same model that went to the moon. Not the plastic version.
Even if the supply of the clone is not constrained, I bet some colours are more popular than others, leading to some natural rarity. And in 50 years if they stop making these things and regular people throw them away, that Pluto watch will be worth more than the Mars and a complete collection will be worth even more. All they have done is create another thing for watch enthusiasts to collect.
I have a more expensive watch but my daily d(r)iver is a Seiko SKX009. Indestructible and with a bracelet upgrade it looks great. And here in Asia you see a lot of marketing for Seiko, and tons of shops. And there’s always Grand Seiko if you want to make watch snobs STFU. Or mods if you want to out-nerd the watch nerds.
I don’t own a Toyota yet but I probably will buy one soon!
