The environmentally friendly biomass plastic is used while maintaining a comfortable fit on the wrist. It is used for the case, urethane band, and resin back cover. Biomass plastic is a high-molecular material that contains substances derived from renewable organic resources as raw materials and is chemically or biologically synthesized to reduce environmental burdens toward the realization of a recycling-oriented society. Castor oil is used for the case and caseback, and biomass plastic made from corn is used for the band. Duplex LCD is used for the watch LCD. The duplex LCD, which has separate LCDs for the azimuth display and the watch function display, provides a larger compass display, improving legibility and making it easier to understand the azimuth in a functional and beautiful design. Furthermore, a rotating bezel is adopted for simple azimuth memory. In addition, by mounting the pressure sensor inside the case, the unevenness of the case is reduced and the buttons are easy to operate. The functional design gives the watch an outdoor gear-like appearance. In addition, the model is packed with high functionality and practicality, and can be used in a variety of situations thanks to the Tough Solar system. Tough Solar -Duplex LCD -Triple sensor capable of measuring azimuth, altitude, barometric pressure, and temperature -Tough Solar -Barometric pressure trend indicator -Barometric pressure trend information alarm -Low temperature resistance (-10°C) -Fully automatic LED light (Super Illuminator) -Tough Solar (solar-powered recharging system) -10 atmospheric pressure water resistance -Tough Solar -Tough Solar -Tough Solar -Tough Solar -Tough Solar -Tough Solar -Tough Solar -Tough Solar -Tough Solar Tough Solar (solar-powered recharging system) ●10 atm water resistance ●World time: 48 cities (31 time zones, with daylight saving time setting function) + UTC (Coordinated Universal Time) ●Azimuth measuring function: measures 16 azimuths and angles (0 to 359°), azimuth continuous measurement (60 seconds), graphic display of east, west, north and south, and bearing memory (azimuth angle) Bearing memory (one graphic showing azimuth angle and recorded direction is stored in memory), magnetic declination correction function, azimuth correction function - Barometric pressure measuring function (measuring range: 260 - 1,100 hPa), barometric pressure trend graph display (displays the past 42 hours), barometric pressure difference graphic, barometric pressure trend Information alarm (notifies you with an arrow and an audible alarm when a characteristic change in atmospheric pressure occurs) ●Altitude measurement function/relative altimeter (measurement range: -700 to 10,000 m), altitude memory (manual memory of up to 30 measurement dates, times, and altitudes, automatically recorded data) Altitude memory (up to 30 manual memories of measurement date, time, and altitude, automatic recorded data: highest/lowest altitude, auto-accumulated (ascent/descent) memory), 14 mountain climbing record data (highest/lowest altitude, auto-accumulated (ascent/descent) memory), altitude difference measurement (-3,000 to 3,000 m), measurement interval setting function (5 seconds / every 2 minutes)*1 second for the first 3 minutes●Temperature measurement Temperature measurement function (measurement range: -10 to 60°C) ● Duplex LC display ● Sunrise/sunset time display ● Stopwatch (1/10 second, 1000-hour counter with split) ● Timer (set unit: 1 minute, maximum set time: 24 hours, measured in 1 second increments) ● Five time alarms (one with snooze function) Battery indicator display - Power saving function (turns off the display after a certain period of time in the dark to save power) - Fully automatic calendar - 12/24-hour display switching - Low temperature resistance (-10°C) - Operation sound ON/OFF switching function - LED backlight (fully automatic light, super illuminator, afterglow function) LED backlight (with full auto-light, super illuminator, afterglow function, and afterglow time switching (1.5 sec./3 sec.))* The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude. When atmospheric pressure changes due to weather conditions, the measured altitude will also change. When measuring outside temperature, remove the watch from your wrist to avoid exposure to body temperature, perspiration (water droplets), direct sunlight, etc. Contents】Main unit, box, instruction manual, and warranty card are included in the instruction manual.
