The best way to answer such questions is to wait and see how the
first wave of watches do in the hands of real people. Yet it’s
not unreasonable for potential early adopters to want at least
some idea before they buy. Lucky for us, Apple is using materials
and techniques that have been standard for wristwatches going
back a few decades, so we can make some educated,
experience-driven assumptions about how the watch variants will
fare on our wrists soon.
