Timekeeping Accuracy - Citizen AQ4103-16E Manual

Timekeeping accuracy

This watch has 5-second accuracy per year.
To maintain 5-second accuracy per year
To maintain this timekeeping accuracy, you must use the watch at ambient
temperature (between +5°C and +40°C) and carry it with you approximately 12 hours
a day.
Please bear in mind that, if the watch is used under any other conditions, the accuracy
may be compromised.
While the insufficient charge warning function is active, the compensation mechanism
to ensure timekeeping accuracy remains disabled. Keep the watch charged at all times.
Accuracy per month
Accuracy per month does not necessarily correspond to 5 second x 1/12. Depending
on the usage environment (temperature change (seasonal change), the duration for
which it is carried, etc.), the accuracy may turn out to be 2 seconds per month.
