Casio has unveiled the Gravitymaster GPW2000-1A, the first Bluetooth connected watch in the brand’s Master of G series. Developed in consultation with aviation experts, it features connected GPS capabilities including Mission Stamp – flight log function that will record time and location and transmit this information via Bluetooth to an accompanying smartphone app.

The Gravitymaster was developed for pilots.

The ‘Masters of G’ range from Casio’s G-Shock represent some of the toughest tool watches out there today. They are feature-packed and developed for use in extreme conditions and aimed at professionals. Take the Gulfmaster for example – it has a barometric pressure sensor that can be used to predict upcoming weather changes, a temperature sensor that detects air and water temperature, and a digital compass that can be used to determine wind and tide direction. Last year, G-Shock introduced the almost indestructible Mudmaster, its most rugged watch yet aimed at rescue crews and Special Forces teams.

The new GPW2000-1A has Casio’s new 3-Way Connected Engine – it uses GPS, radio wave and internet servers (via a Bluetooth link with a smartphone) to provide accurate time anywhere in the world by automatically updating internal data on time zones and daylight savings time (DST).

Casio recently announced that it will be using internet servers to provide more accurate time on its connected watches. It says this will keep the watch updated to accurate time across different time zones better.

The watch is characteristically built tough.

The watch’s most unique and practical feature is designed help pilots manage their flight logs. Pilots can now record details of their flight and view them on the accompanying smartphone app. The Flight Log function can record location and time data when a button on the watch is pressed.

The information can be retrieved from the app and a simulation of the entire flight can be seen as a video, which is very cool feature indeed.

The design of the Gravitymaster’s dial is designed to evoke the image of cockpit indicators. Acquired positioning data is easily viewed, again a first for the Gravitymaster master. The latitude is displayed the in-dial at the 9 o’clock while longitude is seen in the small window at 6 o’clock.

This is the first connected Master of G watch.

The new Gravitymaster features a screw-free construction to secure the band, eliminating the use of screws, which can loosen due to vibration. Instead, the watch employs a fine resin shaft cover and fine resin parts reinforced with a carbon fibre insert to secure the band.

Each model also comes equipped with standard G-Shock technology of shock resistance and 200M water resistance, as well as magnetic resistance, a full auto super LED light, dual-dial world time (auto time zone, 28 cities + UTC), a daily alarm, and a 24-hour stopwatch and 24-hour countdown timer – all in a giant 57.1 mm case. The watch is set to retail at $800 and will be available from May 2017.
