Case/bezel material: Resin Resin band Shock resistant structure (shock resist) Inorganic glass Water resistant to 20 ATM Tough solar (solar charging system) Radio wave reception function: Automatic reception (up to 6 times/day) (Chinese radio waves up to 5 times/day) /Manual reception, <Japan reception radio wave: JJY, frequency: 40kHz /60kHz (model compatible with both Fukushima and Kyushu stations) <Received radio waves in North America: WWVB, Frequency: 60kHz <Received radio waves in Europe: MSF/DCF77, Frequency: 60kHz /77.5kHz<China Received radio wave: BPC, frequency: 68.5kHz *If you set the home time setting to a receivable city, you will receive stations tailored to the city.The time difference will be set depending on the selected city.Direction measurement function :Measure 16 directions/direction angles (0 to 359 degrees), Continuous direction measurement (60 seconds), Graphic display of east, west, north, south, Bearin memory (memory of one graphic indicating the angle of azimuth and recorded direction), magnetic declination correction function, direction correction function Barometric pressure measurement function (measurement range: 260 to 1,100 hectopascals), barometric pressure trend graph display (past 42 hours) , atmospheric pressure difference graphic, atmospheric pressure trend information alarm Altitude measurement function/relative altimeter (measurement range: -700
~10,000m), altitude memory, altitude difference graphic, altitude difference measurement (-3,000 to 3,000m), measurement interval setting function (every 5 seconds/2 minutes), temperature measurement function every 1 second for the first 3 minutes (measurement range: -10 to 60 degrees) World Time : Time display in 48 cities around the world (31 time zones, daylight saving time setting function) + UTC (coordinated universal time) Sunrise/sunset time display Stopwatch (1/100 second, 1000 hour meter, with split) Timer (set unit: 1) minutes , Maximum set: 24 hours, measured in 1 second increments) 5 time alarms (only one with snooze function), time signal indicator display Power saving function (turns off the display after a certain period of time in a dark place to save power) Full auto calendar 1 2/24 hour display switching Operation sound ON/OFF switching function LED backlight (with full auto light, super illuminator, afterglow function, afterglow time switching (1.5 seconds/3 seconds)) No solar power generation from full charge driving time in When using the function: Approximately 8 months When in power saving state: Approximately 23 months Home time city (cities that support reception function) / Received radio waves Tokyo, Seoul, Taipei / Japanese standard radio waves JJY40 / JJY60 (Hono
Lulu), (Anchorage), Vancouver, Los Angeles, Edmonton, Denver, Mexico City, Chicago, New York, Halifax, St. John's/American standard radio WWVB Lisbon, London, Madrid, Paris, Rome, Berlin, Stockholm, Athens, ( Moscow) / British standard radio MSF / German standard radio DCF77 Hong Kong, Beijing / Chinese standard radio BPC () Cities within ( ) may receive reception if conditions are good. When radio waves are not received, it operates with normal quartz accuracy (average monthly difference of +-15 seconds).The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude.When atmospheric pressure changes due to weather conditions, the altitude of the measured value When measuring the outside temperature, remove the watch from your wrist to prevent it from being affected by body temperature, sweat (water droplets), direct sunlight, etc. Size (H×W×D)/mass: 55.2×53.5×18.2mm/93g
