Reminds me of an old joke. My father's watchmaker (back in the 1980s) used to say "The Rolex is an excellent $800 watch." (He was talking about Stainless Steel Sub, not TT or Gold.) At that time a SS Sub would set you back about $3k, so you may adjust his comment for inflation.
I think he was right! You look at the 1980-era SS Sub and, apart from the movement, the quality of materials and craftsmanship can easily be duplicated for $800. Right down to the plastic crystal.
And hell, I'd take a well-tuned 2824 over a 3135 cal. any day, for that matter. It is every bit as robust and capable of same accuracy. Will it last as long? Very likely yes.
So my answer---It depends on the quality og the replica, and the model being replicated. SS Sub yes, TT Sub no. Precious metals and proprietary complications (ie--Seiko Spring Drive) are different matter altogether.
