G-Shock GGB100-1B

Product Information

Casio state that the watch has a +/- 15 seconds per month. I find with many Japanese manufacturers they understate their accuracy and given that the watch synchs with your app you’ll usually always have total accuracy for the current time wherever you are. Size and Fit seconds continuous measurement., A built-in direction sensor detects magnetic north displaying both this and your current direction on the watch face., Bearing Display: Indicates your course against a recorded bearing, Measuring Range: 0 - 359 degrees, Measuring Unit: 1 degree Others: Relative altitude readings (±100 m /±1000 m), selectable measurement interval: 5 seconds or 2 minutes (1 second for first 3 minutes only) Step count (A built-in 3-axis acceleration sensor begins counting steps the moment you start to walk.) CASIO WATCH+ World Time lets you select from among approximately 300 cities as the World Time City, Displays the current time in major cities and specific areas around the world

For the tactical professional or serious enthusiast, the GWG1000-1A1 is tough to beat. It comes with Multi-Band 6 Atomic Timekeeping and Triple Sensor capabilities (altimeter/barometer, compass, and thermometer), ensuring that you're never off-course. The Vibration Resistant Structure adds an extra layer of durability, especially for those in seismic research fields or construction.Official Casio Description. From the MASTER OF G Series MUDMASTER, the watch that is designed and engineered to withstand rough land environments, come carbon resin models that incorporate a new type of structure. A built-in air pressure sensor measures ambient air pressure and presents this on a display to indicate weather patterns, Display range: 260 to 1,100 hPa (7.6 to 32.5 inHg), Display unit: 1 hPa (0.1 inHg), Pressure tendency graph: Changes in air pressure are represented on the watch face in the form of a graph

A built-in direction sensor detects magnetic north displaying both this and your current direction on the watch face., Bearing Display: Indicates your course against a recorded bearing, Measuring Range: 0 - 359 degrees, Measuring Unit: 1 degree Daily Alarms: Each will sound every day at the time you set, Hourly time signal: The watch beeps every hour on the hour Designed to work even in the harshest environments, MASTER of G specialty watches take timekeeping to new heights with a rugged design accented in the bright yellow used for emergency rescues. Update (June 2019): Casio Europe now has the GG-B100 models listed. Other info and features not previously mentioned include: A built-in temperature sensor measures the ambient temperature around the watch and displays it on the LCD, Measuring range: -10°C to 60°C (14°F to 140°F); measuring unit: 0.1°C (0.2°F)

A built-in pressure sensor measures barometric pressure, which is converted to relative altitude, Altitude Graph: Changes in altitude are represented by a graph on the watch face, Measuring range: -700 to 10,000m (-2,300 to 32,800ft), Measuring unit: 1 metre (or 5ft) I have a couple of small gripes after a solid week of testing. Firstly the lume on the hands should extend to the numbers on the dial too or at the very least an extra single lume dot at the 12 position. This means that in the pitch dark you know ‘which way up’ the watch is and more importantly don’t read the watch with a slightly crooked wrist and inaccurately guess which hour it is. There are times when you don’t want to use the LED night to preserve night vision so being able to accurately know you are reading the dial ‘square’ is important. Conquer tough terrain and grab attention with a rugged timepiece boasting a bold, eye-catching color scheme.

The carbon fiber bezel is made with a carbon fiber sheet inserted into the fine resin. The top fine resin layer is transparent which allows the the carbon fiber to be visible.The bezel is formed of three layers of fine resin with carbon fiber inserts. The top layer is transparent, resulting in a bezel that shows the embedded carbon material. The compass might be the best feature on this watch. When you press the top right button you get the seconds hand now pointing north for you AND a digital readout in bearing degrees for the direction you are currently facing. You can also change this readout to a NSEW readout rather than a specific bearing. The watch also allows you to drop a virtual pin on a location and then have the watch indicate direction for you to return to that location later. Battery
