The last time I looked inside a quartz watch, I couldn't find a trimmer,
to my (mild) annoyance.

It was a Timex, if that is in any way relevant.

What do you need a trimmer for IF it has been set properly at the

A trimmer can be used to correct for quartz aging, on a digital watch.

Even if a watch is "perfect" when it leaves the factory, it won't
be perfect any more in ten years time.
