I don't really know about sourcing market data, but this[0] page cites Deloitte and Pew:

>The global smartwatch adoption rate has reached an impressive 21.7% of the adult population

...

>The adoption rate of smartwatches is expected to continue growing, with industry projections suggesting that it will surpass 25% of the adult population shortly.

I don't believe a fifth or a quarter of the adult population could rationally be called 'niche'.
