As I stated in another (trainwreck of a) thread, this may warrant a new thread.
Regarding accuracy of quartz, my observation has been that they work much better as a daily wear than as part of a rotation. The four quartz watches that I can remember wearing over the decades before I jumped down the WUS rabbit hole all performed within 1-3 seconds per month. They were all worn pretty much 24/7. I think being on the wrist keeps the temperature of the watch/oven consistent, which is good for accuracy. I would always set to NIST or time.is when the date needed attention every 61 days. None of the quartz watches were ever off by more than 5 seconds. Usually 1-3.
OTOH, a few years ago, when I started a "DST quartz accuracy challenge" thread, all the quartz watches I checked over the course of 6 months were disappointing in comparison. The watch that is velcroed to my riding jacket sleeve does not display impressive accuracy either. The jacket watch is a $15 Casio. Several of my current quartz watches cost considerably more than anything I wore pre-WUS.
So this is probably the wrong crowd to ask, but any superlative quartz accuracy stories? Or horror stories?
