Casio G-Shock GDF100 Watches
Auto-LED light
A light-emitting diode (LED) is used to illuminate the watch face, incl. the
feature of an Auto Light Switch that illuminates the display when the watch
is angled towards the face.
Shock resistant
Shock-resistant construction protects against impact and vibration.
Low-temperature resistant (-10 °C)
Even temperatures as low as -10 °C have no effect on this watch.
10,000 m Altimeter
A pressure sensor detects changes in the air pressure and converts the
result into an altitude up to 10,000 m.
Barometer (260/1100)
A special sensor measures the air pressure (measuring range: 260/1100 hPa)
and presents this on the display in the form of a symbol. This enables early
detection of weather trends.
Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature around the watch and displays it
in °C (-10°C /+60°C).
World time function
Displays the current time in major cities and specific areas around the
world.
Stopwatch function - 1/100 sec. - 24 hours
Elapsed time, split time and final time are measured with 1/100-sec
accuracy. The watch can measure times of up to 24 hours.
Timer - 1/1 min. - 24 hours
For fans of precision: the countdown timers help you to remember specific or
recurring events by giving off an audible signal at a preset time. The time
can be set to the nearest minute and up to 24 hours in advance. Ideal for
people who need to take medicines every day or those who do interval
training.
5 daily alarms
The daily alarm reminds you about recurring events with an acoustic signal
at the time you have set. You can also activate hourly time signal that
indicates each full hour. This model has 5 independent alarms for flexible
reminders of important appointments.
Button tones on/off
The button tones for using the mode button can be turned off. This means
that the watch no longer beeps when switching from one function to another.
Preset alarm or countdown timers remain active when the button tones are
deactivated.
Automatic calendar
Once set, the automatic calendar always displays the correct date.
12/24-hour timekeeping
Times can be displayed in either a 12-hour or 24-hour format.
Resin case
Resin band
Natural resin is the ideal material for wrist straps thanks to its extremely
durable and flexible properties.
3 Years - 1 Battery
The battery supplies the watch with sufficient energy for approx. three
years.
Water resistance classification (20 bar)
Perfect for free diving without scuba gear: the watch is water resistant to
20 bar / 200 metres. The metres value does not relate to a diving depth but
to the air pressure used in the course of the water resistance test. (ISO
2281)
