But do you know [whether] any voltage drop is really NEEDED?

Gee, Phil, I thought you were omniscient.

Though you'd think the mechanical nature of the Accutron's timekeeping
process would remove any interaction with the electronics, it's not so.

The user manual specifically states that the watch runs a bit fast with new
cells, until their initially slightly high voltage "settles in" to its
nominal value. Therefore, an Accutron will run fast with modern cells.
