From Casio G-Shock, the innovators of tough timekeeping, comes the GGB100 Master of G Mudmaster watch series that has been designed to endure the toughest environments.
This watch features a carbon core guard structure case, in black with grey accents, that allows the internal mechanics of the watch to be protected from shock-induced damage.
Additionally, this watch connects via Bluetooth to a special G-Shock app that helps with the configuration, as well as records altitude data, route information, and step counts.

This timepiece features a 45.6mm black stainless steel case that is just 8.9mm thick, which is 30% thinner than the previous Casio Edifice smartphone link watches.
Smaller in size but not in capability, this multi-hand chronograph watch boasts an Accurate Time System that automatically establishes a Bluetooth(R) connection with your smartphone four times a day to update current time settings.
In addition, Bluetooth(R) technology offers a range of functionality when paired with your smartphone via the Casio app, including automatically updating of the time when changing time zones, synching the time to atomic clock signals via the internet, the ability to control watch functions, ping your phone if it's lost, and more.
As well as being connected, this watch also features a Tough Solar power system that enables charging by light, even by exposure to fluorescent light.
