G-Shock by Casio
From G-SHOCK, the watch that is constantly testing new limits in timekeeping toughness, comes a new series with Carbon Core Guard structure, which takes toughness to a new level. The case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin. This material protects the internal module from shock-induced damage and deformation. The dual back cover protects the back surface against impact. Button structure shock resistance has been improved, which eliminates the need for external button guards. The face of the watch consists of a disk pointer and raised hour markers for a look of bold toughness. This watch features mineral glass face, shock resistance, carbon core guard structure, 200m water resistance, double LED light, world time (31 time zones), 1/100 second stop watch, countdown timer, 5 daily alarms, hourly time signal, hand shift feature (hands move out of the way to provide an unobstructed view of digital display contents), full auto-calendar (up to year 2099), 12/24 hour formats, button operation tone on/off, approx battery life: 3 years on SR726W x 2, size of case/total weight: 51.2 x 48.7 x 14.1mm/ 64g
