"It must be understood that a chronometer is not a "clock"."
I'm afraid I only know the modern use of the term, i.e. that a wristwatch having
passed certain ratings is now "certified" as a chronometer, as Rolex does. Can
you tell me what makes a chronometer not just a clock, in the larger sense? And
what accuracy you expect from a true chronometer?
