The Citizen Chronomaster (A060): 6 Month Accuracy

This The Citizen Chronomaster AQ4041-54L has the A060 movement which is rated to be accurate within +/- 5 seconds per year. I will track its performance over a year to validate that claim. Please note that this is a JDM watch, meaning that it is sold primarily in Japan.

Six months after synchronization, it appears to have 2.5 seconds of deviation. It should become clearer as the year progresses how well this watch keeps time.

The digital watch seen here is the Casio G-Shock GWM5610U. In previous videos I used an analogue clock app on a smartphone, which represented Internet time, to make my comparisons. For this video I'm using the radio-controlled watch, which was synced to atomic time overnight. The time difference between these two methods is negligible, and any error cancels out over a repeated long-term test.
