Feel the Field
Advanced measurement functions benefiting from
miniaturised sensor technologies monitor the constant changes
in natural phenomena with reliable accuracy.
A watch that combines the utility required of an outdoor tool with the precision of
a fine-quality timepiece, PRO TREK is constantly evolving and exploring new fields.
Triple Sensor, Ver. 3
+ Tough Solar
+ 10-bar Water Resistance
Triple Sensor, Ver. 3
Three miniature sensors for measuring directions, barometric pressure / altitude, and temperature: These comprise PRO TREK’s core technologies for high-precision detection of sudden changes in natural phenomena. In 2013, CASIO has developed a dramatic upgrading of Triple Sensor’s with its advance to a 3rd generation.
Triple Sensor’s History of Evolution
Triple Sensor, Ver. 1 (1994-2001)
Triple Sensor debuted in 1994. Operating on battery power, it revolutionized the wristwatch with its ability to measure directions, barometric pressure / altitude and temperatures.
Triple Sensor, Ver. 2 (2002-2012)
A Triple Sensor with CASIO’s original Tough Solar rechargeable solar battery system providing the power required to conduct sensor measurements.
Next-generation Triple Sensor realised through advanced sensor technologies
Ver. 3 (2013)
90% Power reduction
Improved measurement accuracy 1m altimeter measurement 1.0 second measurement
- Sensor functional innovation
|Triple Sensor, Ver. 2||Triple Sensor, Ver. 3|
|Altitude measurement||Measurement unit||5m||1m|
|Shortest measurement interval||5.0 seconds||1.0 second|
|Measurement accuracy||Altitude change x 2%||Altitude change x 0.3%|
|Pressure measurement||Measurement accuracy||Barometric pressure difference x 2%||Barometric pressure difference x 0.3%|
|Direction measurement||Continuous measurement duration||20 seconds||60 seconds|
*Measurement accuracy under constant temperature
- Sensor power savings / Downsizing
|Pressure sensor||1/7 as compared to second generation|
|Direction sensor||1/10 as compared to the second generation|
- Case size
*Case dimensions excluding protruding buttons/sensor cover
Barometer / Thermometer
- Radio-controlled (Multi Band 6)
- 10-bar water resistance
- Barometric pressure
A barometric pressure tendency alarm has been installed to alert wearers of any notable change, such as a sudden drop or rise, in barometric pressure.
- Full auto
The high-brightness LED light senses illumination levels and switches on automatically with just a tilt of the wrist.
Large direct buttons
Direct buttons enable one-push direction, barometric pressure / temperature and altitude measurements. Constructed of solid metal, they are treated with anti-slip processing and built to oversized dimensions to permit easy operation, even while wearing gloves.
Soft urethane band
The band offers a smooth, supple fit, despite its high-level stretch-resistance and durability.
Icons positioned near the various direct buttons facilitate intuitive identification of their functions, which include direction, altitude and barometric pressure measurement.
