Chronographer

Periodically collect data points comparing a watch’s time to the current correct time. Chronographer stores this information and uses it to create charts tracking each watch’s offset (the difference from the correct time) and deviation (how many seconds it’s gaining or losing per day). Graphs show individual data points and best-fit trend lines over various timespans. Histograms provide insight into how offset and deviation values are distributed. Chronographer also calculates detailed metrics about each watch’s accuracy.
