You'd probably find that modern watches aren't much more-accurate
than an Accutron.

I had an earlyish quartz watch that was achieving a minute a year, which
in practical terms meant it only had to be reset at daylight saving time
changes. It's true I've seen nothing that accurate since.

And I would be dishonest if I didn't admit my Casio Edifice watch is
accurate to within a few seconds a month.
