That is in general a ridiculous claim to make when talking about consumer technology. No company has a decade-long lead in anything. If there is sufficient economic motivation competitors will always catch up in a year or two. It happened for smartphones, tablets, TVs, speakers, headphones, cameras, voice assistants and just about everything else.

In case of the watch specifically I actually think there isn't enough motivation to innovate considering the space hasn't blown up like everyone expected. If you take headphones out of the picture wearables as a whole is still a relatively niche device category.
