Another Baselworld 2018 introduction is the G-Shock GR-B100 Gravitymaster series. The GR-B100 is a Tough Solar analog-digital aviation model featuring a “high definition” LCD display and large analog hands. The analog subdial appears to be a countdown timer and function indicator. The GR-B100 can connect to a smartphone via Bluetooth and the G-Shock Connected app can adjust the watch settings and automatically sync the time. This watch also has the flight log function which records time and location point information and presents the log data on a map in the smartphone app. A special countdown alarm feature allows the time, date, and schedule name to be set, with the remaining time to set time shown in the LCD display. This feature allows counting down to a specified date and time rather than just a time, and the countdown to each event can be displayed on the watch to the exact second.
Features include shock resistance, 200-meter water resistance, Tough Solar, Bluetooth, world time, 1/1000 second stopwatch, 1/10 second countdown timer (24 hours), 5 multifunction alarms (countdown with date), and Super Illuminator LED light with afterglow. The GR-B100 measures 62.5 x 53.8 x 17.3 mm and weighs about 87 grams.
The debut models are the GR-B100-1A2 (left), GR-B100-1A3 (middle), and GR-B100-1A4 (right) featuring dual-layer resin bands. The GR-B100 line is scheduled for a release around June 2018 with a list price of around $300 USD (though exact release details are not yet confirmed).
