Casio G-Shock G-Rescue Black Resin Digital Tough Solar Alarm Chronograph Mens Watch GW-7900-1ER   This Casio G-Shock G-Rescue Tough Solar Alarm Chronograph Mens Watch GW-7900-1ER 50mm is a great addition to the G-Shock family.

The day, date and month are displayed at the top of the dial with the real time being centered to the bottom of the dial. At the right side of the dial is a simplistic chronograph used to measure time. The super-chunky case is built to the same exact standards as the entire G-Shock range, and is a matte finish black with grey detailing. It is secured on a thick rubber strap with secure double tang buckle, and pieces between the case and strap to allow extra movement for added comfort. This watch has a water resistance of 200 metres, making it suitable for diving.

The company entered the timepiece market in 1974 with the release of the Casiotron, the world’s first Auto Calendar watch. Only eleven years after entering this field, Casio completely reshaped global thought about the function a watch should perform with the release of the pioneering and now legendary G-Shock family. Innovation and world firsts have defined the company’s history ever since, the most striking of these being the release of the first ever touch screen watch in 1991, 24 years before the Apple Watch, and the first ever wrist camera watch in 2000. In short, Casio was producing smartwatches decades before the term had even been coined. Add to this the hipster popularity of the company’s retro designs, and Casio has firmly cemented its reputation as a famously reliable and precise name in both analogue and digital watches.
