- A real Rolex dive watch costs $5k-15k.
- A similar Swiss-made dive watch from a less famous brand costs $2k-4k.
- A similar Japanese-made dive watch from a famous brand costs $500-1000.
- A Chinese-made replica/fake Rolex, mechanically identical to a real one, and only distinguishable by an expert under high magnification, costs about $400-800.
- There are some low-volume watches that are sold for 4-6 figure sums to repeat buyers. Richard Mille in particular has done one-offs for celebrities in the range of 7-8 figures.
As you can imagine you don't need a high volume with margins that large.
