...that when it comes to non-thermocompensated quartz, you never know when you're picking a winner or a loser.
I decided to nerd-up and conduct a long term accuracy test of four reqular quartz watches I have. I set all three of them to time.gov 102 days ago, and today I used the stopwatch method to check how much they had deviated. I then took that error rate and divided it by 102 days to give me an average daily error rate. Then I multipled that number by 365 to give me a yearly error rate.
The results were surprising.
