Product description

These are the latest additions to the G-SQUAD lineup of sports watches from G-SHOCK, which are equipped with heart rate monitor and GPS. Useful workout functions include an optical sensor for heart rate measurement, along with bearing, altitude/barometric pressure, and temperature sensors, and an accelerometer for step counting. These five sensors help to keep you in close touch of your current activity in real time. The ability to receive GPS signals lets you access location information when you need it. This, when used in combination with the stopwatch, makes it possible for you to keep track of running information like distance, speed, pace, and more. Your heart rate and speed is used to calculate a VO2 max value, which is an indicator of your cardio-pulmonary capacity. This measurement is useful when trying to increase stamina for running and other activities. In addition, new phone apps are now available to help you configure watch settings more easily and manage your workouts. You can monitor your current fitness level and training progress, and even automatically create a training plan based on targets specified by you. VO2 max calculation and other data analysis capabilities use a library by FIRSTBEAT, a renowned sport science company. Algorithms of improved accuracy support a higher level of training. The surface form of the back covers of these models reduces interference with the back of the hand, while a soft urethane band provides a better fit to the wrist. Bi-color molded buttons are designed for ease of use, while a high-definition MIP LCD makes display information more legible. Both USB and solar charging are supported, and solar charging can be used to power daily operation (except for pulse monitoring and GPS). Renowned G-SHOCK toughness along with new outdoor functions for a new selection of G-SQUAD timepieces.

Casio G-SHOCK Move GBDH1000-8

The new GBH1000 G-SHOCK Move watch is equipped with heart rate monitor and GPS. Useful workout functions include an optical sensor for heart rate, along with bearing, altitude/barometric pressure, and temperature sensors, and an accelerometer for step counting. These five sensors help to keep you in close touch of your current activity in real time. The GPS feature allows you to access location information when needed. When used in combination with the stopwatch it makes it possible for you to keep track of run information like distance, speed, pace, and more.

The GBDH1000 is equipped with an optical sensor on the caseback of the watch. The LED light detects the blood flow under your skin and measures heart rate. Based on your heart rate and running speed, VO2max (maximum amount of oxygen you can utilize during exercise) is calculated to inform you if working out efficiently or not. This is achievable thanks to the utilization of Firstbeat technology. Firstbeat uses a unique algorithm to provide advanced performance analytics.

GPS Route Mapping

GPS functionality measures distance and tracks movement when running. The built-in GPS feature acquire data from GPS, GLONASS and Michibiki satellite systems. Link to a smartphone and you can access a map display of routes traveled. Additionally, GPS signals are received to adjust watch time, date, and time zone. (*when automatically adjusting time while paired with a smartphone, GPS auto-signal reception is off)

The G-SHOCK Move APP receives training data from your watch and provides detailed information of your training activities. Increase motivation by managing measurement data and training history with the APP, which automatically creates training plans tailored to set targets. On top of managing your workouts on the G-SHOCK Move APP, you'll be able to easily configure your watch settings.

Five Sensors

• Heart Rate Monitor
• Accelerometer
• Digital Compass
• Altimeter
• Barometer/Thermometer

Tough Solar Charging

Integrated Solar Panel That Uses Sunlight and UV Light to Recharge the Watch’s Battery. GBDH1000 is also equipped with USB charging capabilities, which quickly charges for training features; after about 2.5 hours of charging, training features can be used continuously for up to 14 hours.

Vibration Alarm

Never miss a notification while listening to music during your workouts! GBDH1000 can be set between normal alerts and vibration notification alerts. The watch will vibrate simple alerts for time elapsed during training and heart rate zone, as well as smartphone email receipt and other notifications.

Super LED

The GBDH1000 uses a MIP LCD (Memory in pixel LCD) which displays various detailed measurement data in a high contrast screen for easy viewing. The MIP LCD is also equipped with a super LED backlight that illuminates the screen with high-intensity light, maintaining watch readability in the dark.

User questions & answers

Question:	What does “Battery life: 5 months” means
Answer:	This is a solar power watch, if left in a drawer for example it should have power reserve lasting that long without exposure to light
Question:	Is there a international warranty card? Thx
Answer:	WARRANTY CARD IS VALID ONLY FOR SERVICE IN THE COUNTRY OF PURCHASE.
Question:	Is this watch made in japan? just to confirm before i place my order. thank you
Answer:	the watch is cased in China
Question:	What exactly does the app do for the watch besides set the time
Answer:	The app primarily syncs the time to your phone but also offers a secondary time zone for travelers as well as alarm and timer but obviously your phone already has those features. The only other thing the app has is the guide that is the instructions for use document. So essentially you are correct, the app mostly is making sure time is exact by syncing with your phone but even so you have to push the red button to update it for daylight saving time changes.
