Product Features:

An electro-lumin escent panel causes the entire face to glow for easy read in g. Auto Light automatically turns on the EL backlight when the watch is tilted towards your face for read in g.

Displays the current time in major cities and specific areas around the world. R : Current time in major cities around the world. 48 : Values indicate number of cities/areas.

Displays approximate Moon phase based on date and time differentials. AGE = Moon age indicator Moon age error : with in + 1 day

Graphically displays tides based on lunar periodicity and lunitidal interval time.

Accurate measurement of elapsed time with the touch of a button. 1/100 : The fraction indicates the unit of measurement. 24 HR : The time figure indicates the maximum time measurement for Stop Watch.

Counts down from a start time specified by you. The value indicates the number of timers available. 24 H : The time figure indicates the maximum starting time.

Multi-function Alarms can be configured to sound on a particular date a particular day of the week or at the same time each day. The number 3 indicates the number of Alarms. The hourly time signal causes the watch to beep every hour on the hour.

Each time you stop the alarm it sounds again after a few minutes.

Battery lasts for at least three years. 7 : The value indicates actual battery life in years.

Allowances are made automatically for months of different lengths including leap year.

Times can be displayed in either 12-hour or 24-hour format.

The tone that sounds to signal a mode change or other operation can be turned on and off.

The 'BAR' value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Wearable around sinks during swimming poolside diving and scuba diving at depths not requiring helium gas.

Hard glass resists scratching.

The unique G-SHOCK design also provides it with the ability to withstand the rigors of water resistance testing up to 20 atmospheres which is equivalent to 200 meters. This means unequalled toughness even under water.

The drop test is performed manually by actually dropping watches. A test machine cannot be used for such a test because there is no way to control or reproduce all of the countless variables involved when an object falls.

The cushioning system of the watch also provide outstanding resistance to vibration. In the past vibration resistance was tested by fixing the watch to the axle of a motorcycle. Today a special test machine is used to subject the watch to vibration for 24 hours to check its ability to withstand such treatment.
