A timely thought

As the days of analog timepieces fade into history, will the directions "Turn clockwise to tighten" soon lose all meaning?

Will the expression persist, complete with scholarly footnotes and diagrams?

What could possibly replace it?

Any youngsters out there who can give a current status report?

And, just for fun, what other words or phrases can you think of that belong to the past but live on in the present? (It's late, and all I can think of right now is "Hold your horses!")
