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.

What a crap design then.

Gareth.

Makes a bit of a mockery of the name "Accutron" ...


No one could have predicted that mercury button cells would be pulled
from the market. The more so because mercury laden twisty bulbs are
becoming all but mandatory.


Pay attention at the back. The comment was made in respect of the fact,
quoted from the user guide, that even with the original correct battery
type, when a new one was fitted, the watch would run fast for a few days
whilst the terminal voltage settled. Gareth suggested, with tongue in cheek
humour that is being misunderstood by William, that this made the design
"crap", a word that is used in the UK with a slightly different emphasis to
when it is used in America. I then followed on, with similar tongue in cheek
humour, that this unfortunate characteristic of the design, made a bit of a
mockery of the fact that the name was obviously based on the adjective
"accurate", which obviously, it isn't for those few days ...

The additional fact that the mercury cells are no longer available, is now
rather unfortunate for this aspect of the design, as the next nearest
available terminal voltage for a cell with the right footprint to fit the
watch, is high enough for the watch to think that it permanently has a 'new'
battery, so permanently runs inaccurately fast. Hence the OP's original
question.
