Official Marketing Focus from Casio
Triple Sensor Version 3, advanced CASIO original technology that makes it possible to pack sensors 95% smaller than those of previous models into a totally new type of compact PRO TREK. Despite their smaller size, the new sensors in this model provides improved reading accuracy and energy efficiency.
This new Triple Sensor Version 3 model delivers altitude, barometric pressure, and direction readings that are more accurate than previous models. A Barometric Pressure Tendency Alarm alerts the wearer to sudden changes in pressure readings, which can indicate upcoming weather events.
In terms of both functions and looks, this Triple Sensor Version 3 provides a choice of outdoor timekeeping gear that can’t be beat.
Official PRW-3100 Specs / Features *for base version PRW-3100YB-1
- Super-Full-Auto LED light
If the ambient light fades, a turn of your wrist illuminates the watch display particularly brightly.
- Low-temperature resistant (-10 °C)
Even temperatures as low as -10 °C have no effect on this watch.
- Solar Power
A solar cell provides power for operation.
- Radio signal reception (EU, USA, Japan, China)
Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China – once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.
A built-in direction sensor detecs the magnetic north.
- Barometer (260 / 1.100 hPa)
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.
- 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.
- Height Gain
The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour.
- Altimeter data memory
Depending on the model, up to 40 sets of elevation data can be stored in the watch’s data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored.
- Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).
- Sunrise/sunset display
After entering the geographical location, sunrise and sunset times can be displayed for any given date.
- World time function
Displays the current time in major cities and specific areas around the world.
- Stopwatch function – 1/10 sec – 1.000 hours
Elapsed time, split time and final time are measured with 1/10-sec accuracy. The watch can measure times of up to 1000 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. This model has 5 independent alarms for flexible reminders of important appointments.
- Snooze feature
Each time you stop the alarm, it sounds again after a few minutes.
- 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 with Date, Day and Month
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.
- Mineral glass
The tough mineral glass resists scratching.
- Resin case
- Resin band
Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.
- Battery level indicator
An indicator shows the current battery level.
- Water resistance classification (10 bar)
Perfect for swimming and snorkelling: the watch is water resistant to 10 bar according to ISO 22810.
- Dimensions (H x W x D)
56,0mm x 47,1mm x 12,0mm

You ask, we answer…
CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.
It’s the electronic mechanism that “estimates” the altitude based on the air pressure.
It measures and displays direction as one of 16 points.
It measures the air pressures and displays tendencies in the weather.
