Casio Protrek Tough Solar Powered Environmentally Friendly Biomass Outdoor Sports Watch with Altimeter, Barometer, Compass, and Thermometer Style PRW-61-1.

Case and urethane band and resin back cover. Biomass Plastic is a polymer material that contains renewable organic resources derived from chemical or biological synthesis and is expected to reduce the environmental load in order to achieve a circulation society. This time, the case and back cover are made of castor oil and the band is biomass plastic based on corn material. The soft urethane band uses a target guide, making it easier to read the direction of the second hand, and has a functional and beautiful design that makes it easier to understand your direction. The dial also features a thick hand and easy-to-read bar indexes for increased visibility. The PRW-61Y is designed with IP on the bezel. As the original function of the watch, it also combines practical functions such as multi-band 6 which receives radio waves from 6 stations around the world and tough solar. This model is perfectly sized for functionality and practicality that is suitable for various occasions. • Tough Solar (solar charging system).Operating time when fully charged without solar power: About 6 months when using functions; when power-saving state; About 25 months • Water-resistant to 10 ATM. • Radio reception function: Automatic reception (up to 6 times per day) (China radio waves up to 5 times per day) / Manual reception Reception radio wave: JJY, Frequency: 40 kHz/60 kHz (Fukushima / Kyus hu station model) Reception radio wave: WWVB, Frequency: 60 kHz If no radio wave reception is received, it will work with normal quartz accuracy (average monthly difference ± 15 seconds). • Automatic needle position correction function. • Needle evacuation function (manual and automatic when altitude, atmospheric pressure, temperature measurement). • World time: 29 cities around the world (29 time zones, with daylight saving setting function) + UTC (Coordinated Universal Time), home city exchange function, UTC direct call function. • Bearing measurement function: Measures 16 azimuth and azimuth angles (0 - 359°), continuous measurement of azimuth (60 seconds), northern direction indicator function, magnetic decagonal correction function, bearing correction function (2 point correction). • Altitude measurement function / Relative altimeter (measurement range: -700 ~ 10,000 m, 1 m unit), altitude difference indicator (measurement range 1:100 m / 5 m units, measurement range 2: 1000 m / 50 m units), altitude trend graph display, measurement interval setting function (5 seconds /2 minutes), altitude memory (measured date, date, time and altitude. 30 pcs Manual Memory), Auto Recording Data (Max/Lowest Altitude, Auto Accumulation (ascend/low) Memory) • The altimeter is a relative altimeter that converts barometric pressure changes to altitude. When the pressure changes depending on weather conditions, the altitude of measurements will change. • Barometric pressure measurement function (measurement range: 260 - 1,100 hPa, 1 hPa unit), pressure trend graph display (displays past 20 hours), atmospheric pressure difference indicator (measurement range: ± 10 hPa units), atmospheric pressure trend information alarm (arrow and alarm will notify you when a characteristic change of atmospheric pressure occurs). • Temperature measurement function (measurement range: -10 ~ 60 ℃, 0.1 ℃ units) • Stopwatch (1/100 second, 24-hour meter) • Timer (measured in increments of 1 minute, maximum set of 60 minutes, and 1-second increments). • 5-time alarms, time signal. • Battery indicator display. • Power saving function. • Fully automatic calendar. • Switch between 12 and 24-hour displays. • Low-temperature resistance (-10 ℃) • Control sound ON/OFF switch. • Double LED Light: Dial LED Light (Full Auto Light, Super Illuminator, Afterglow Function, Afterglow Time Switching (1.5 sec/3 seconds), LED Back Light (Full Auto Light, Super Illuminator, Afterglow Function, Afterglow Time Switching (1.5 sec/3 seconds)
