OK, this one will be controversial. A chronometer is a specific thing, at least to
link me, and whether rightly or wrongly, it should be
link a watch that has been verified to be precise within the -4 to +6 seconds per day. This is how the Contrôle Officiel Suisse des Chronometres (COSC) defines it, and it's how I learned it way back in the day. The literal Meriam-Webster definition is a "timepiece, especially one
link designed to keep time with great accuracy despite external forces."
