Speaking as a quartz watch nerd, I enjoyed these articles
I have had several of the watches & clocks mentioned, and a few others.
Citizen Chronomaster
Grand Seiko High Accuracy (denoted by single star on dial)

Another one

The second generation Quartz Astron (before Astron name was dedicated to the radio/satellite watches) the case is titanium / ceramic

Astron Movement; notice the adjustment provisions down at bottom right of movement



The Longines VHP (very high performance?)
My Glashutte marine chronometer clock (exploded views)

My reference clock driven by satellite broadcast (external antenna on roof) as accurate as we civilians can get (aka legal time).
