Set contents: Main unit, box, Japanese manual for handling, and a certificate of assurance are attached to the Japanese handling manual [Shockproof Construction & 20 Atm Waterproof] Adopts a shockproof design that is high against shock and vibration. It is also equipped with 20 bar water resistance, so it can be used in a wide range of places and situations. [5-SENSOR: Measure activity in real time with 5 types of sensors] Optical sensor (heart rate monitor): Equipped with an optical sensor on the back of the main unit. Detects blood flow in the system by illuminating LED light, measures heart rate/accelerometer: Detects physical movement with a 3-axle accelerometer, and measures maintenance or travel distance. Distance measuring in an area where GPS cannot be recorded is also interpolated. /Azimuth, altitude, barometric pressure/temp sensors: Measure altitude, air pressure/azimuth, and temperatures with built-in small sensors. The azimuth and altitude information helps to make GPS distance measures more accurate. [GPS function measures distance and tracks movement during driving] GPS function: Acquire current location information from GPS satellites. Measure distance, speed, and pace of movement. In addition to GPS, it is compatible with GLONASS and Mibiki. /Displaying travel routes: By partnering with a smartphone, it is possible to display a map of the travel trajectory on the app. /Automatic time change: By receiving GPS radio waves, it is possible to set the watch's time, date, and time zone. ※ When pairing with a mobile phone to automatically set the time, the auto reception of GPS radio waves is omitting. solar charging system/charging system with contact charger/GPS radio reception function/manual receiving/training function/manual lap function, auto pose function, auto pose function, auto driving measuring start function, arrival alarm setting function, ON/OFF switching function, training display personalization function/wrist-type heart rate measuring function: heart rate, goal heart rate setting function, heart rate zone graphic display, heart rate transition graphs, maximum heart rate, minimum heart rate/training data, training record data/user profile setting function/mobile link function/azimuth measuring function/barometric measuring function, air pressure-trending graphs, air pressure-trending information alarm/altitude measuring function/relative altimeterization, altitude change MEASURING/TEMPERATURE MEASURING FUNCTION/VIRATION FUNCTION/ World Time/ Stopwatch/ Timer/ VISUAL ALARM/ Indicator Display/ Power Saving FUNCTION/FULL AUTO CALENDER/ 12/24 Hour Display Toggle/In-flight Mode/Operation ON/OFF Switch FUNCTION/LED Back Light Be sure to check the detailed product description at the bottom and the points to keep in mind when making a purchase before making a purchase!
