You don't see any problems at all with taking my sentence, "It will cost you significantly more than a lifetime supply of quartz watches", truncating off "of quartz watches", and responding as if I had said "of smartwatches"?
A quartz watch will do everything a Rolex will do, and more, while keeping more accurate time. A smartwatch will do significantly more than a quartz watch will.
People who believe that, are going to spend an awful lot more on smart watches, than a Rolex costs, in the next 10 years.
