● Be sure to replace the battery as soon as it runs down, and not to leave a discharged battery
inside the watch.

* The watch will, however, remain accurate while the second hand is moving at two-second intervals.
● To show when the battery must be replaced, the expected time (month and year) for the first
battery replacement is inscribed on the case back as shown in the illustration below.
