Function and Feature
LED Light (Full Auto Light) - A light-emitting diode is used for display illumination. The Full Auto Light feature illuminates the display when the watch is tilted towards the face, only when lighting is dim.Solar Power - A solar cell provides power for operation.World Time - Displays the current time in major cities and specific areas around the world. R: Current time in major cities around the world. Values indicate number of cities/areas.Stopwatch - Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement.Timer - Counts down from a start time specified by you. The value indicates the number of timers available, while the time figure indicates the maximum starting time. "REPEAT" indicates Auto Repeat, which automatically restarts timing at the end of each countdown.Daily Alarm, Hourly Time Signal - The daily alarm sounds each day at the time you set. The value indicates how many daily alarms are available. The hourly time signal causes the watch to beep every hour on the hour.

Watches marked "200m" have the same water resistance as 20 BAR watches.
Neobrite - A luminous coating provides long-term illumination in the dark after only short exposure to light.Mineral Glass - Hard glass resists scratching.Resin Band
