Record title On December 12, 2017, the G-Shock earned the Guinness World Record for the heaviest vehicle to drive over a watch. The officials from Guinness World Record drove a 24.97-tonne truck over the Casio G-Shock DW5600E-1. The G-Shock is the first watch by any company being able to withstand the challenge. List of models Master of G The Master of G series is the speciality line of G-shocks which were used to introduce new features that would eventually make their way to the standard production models. The lineup consists of: Frogman Wademan Raysman Lungman Fisherman Riseman Gaussman Seaman Antman Gulfman Rangeman Mudmaster Gulfmaster Gravitymaster G-Lide Surfing editions These models were released in 1996, designed and specifically made for the surfing market. The countdown timers on these models were designed to count down for surfing competitions, some of the later models have a yacht timer, moon and tide graphs so a surfer can keep track of the progress while competing on the water. Many of these models came equipped with a pair of strap adapters and a single one-piece resin or nylon band. These styles of band are also known as "crossband" in the Japanese domestic market. Resin bands for these models had open gaps or slits through the band. Casio refers to them as drainage slits; the idea is that water will drain out with no problems while in action when surfing. Most of these series models had a translucent band. These models were branded as X-Treme for the Japanese domestic market. X-Treme Snow Board/Skateboard Editions These models are identical to the surfing editions, and also released in 1996. They were designed for snowboarding and skateboarding competitors and competitions. The only difference is that these models came with nylon velcro bands.
