I have had a love-hate relationship with accuracy and precision for most of my life. In high school, I used to set my Timex watches to the school bell, so that when my watch hit the mark, class was let out. When I was on the drill team in the Royal Canadian Air Cadets, synchronizing our marching was critical and our timing had to be impeccable. I also grew up in a household that firmly believed that if you were not at least 10 minutes early, you were late. The latter has led me to sit on many empty Zoom/TEAMS calls for 5-10 minutes, but at least I am never late.
It has been the same with the accuracy and precision of my mechanical watches. As a serial watch monogamist, I cannot wrap my head around owning multiple watches and swapping one out for another every other day. I just can’t do it. Instead, I wear my watches 24/7 and try to get the very most I can out of ownership. I track both the accuracy and precision of each piece, as well as how it wears and how the watch changes over time.  Now you may be asking yourself, why is he talking about accuracy and precision as if they were two different aspects of timing. To me, they are distinct. Accuracy is tracking how well a watch keeps time versus established atomic timing, such as www.time.gov. Precision is how precise the time is displayed on a watch. More on this later. For now, let us focus on accuracy.
