Readability in the dark is enhanced by a dual Super Illuminator LED light, which illuminates both the analog dial and the digital display, with a customizable illumination duration ranging from 1.5 to 3 seconds (illustrated by an icon of a person looking at their watch at night). The watch also features a world time function covering 38 time zones and 38 cities, a 1/100-second stopwatch for measuring time intervals of up to 24 hours, and a timer adjustable up to 60 minutes.

You can set up to 5 daily alarms and turn on the hourly chime to stay organized throughout the day. The watch features a full automatic calendar valid through 2099, a mute function to disable button sounds, and a hand-shift function that clears the digital display for better readability.
