That would be disappointing! If you're charging $100,000 for a damn watch, it had better beam the time directly into my brain at all times.

That's not accurate.

There are ergonomic variants of keyboards on the market. There is no viable alternative to the way how we measure time.

There are digital and 24 hour variants that are not only viable, but common.

I think they are posting about how time is displayed, not measured. Digital watches seem fairly viable.
