Casio GBD-300-1DR G-Shock Men’s Watch

Introducing the GBD-300 line for your active everyday — the tough, sports-oriented G-SQUAD designed to make training fun. Find more joy in your workout with the GBD-300, packed with practical functionality to support running and other training regimes. With accelerometer, distance tracking, Smartphone Link, high-resolution display, and more, this G-SQUAD has you covered — from managing your everyday health to improving your endurance. Use the GPS functionality of a paired smartphone to adjust distance measurements, after which the watch can measure running distance more precisely even when not connected to your phone. Equipped with Auto Lap, the watch also tracks running pace and automatically keeps track of times over a set distance. Tap into the dedicated app for visuals that help you see your own personal records and easily manage life log data and activity history. Set the watch to vibrate, alerting you to time elapsed, calories burned, and other milestones during training, and you won’t miss any telephone, email, and social media notifications, either. The display features high-resolution memory-in-pixel (MIP) LCD and Super Illuminator. Together with the auto-light function, which automatically lights with just a tilt of the wrist during running, the GBD-300 ensures visibility, even at night. Thanks to a shock-resistant structure that places the case between a front bezel and a back bumper bezel, the GBD-300 boasts the slimmest profile of any G-SQUAD. Made of soft urethane, the band offers an even more comfortable fit with band holes placed at 5mm intervals for finer adjustments for a variety of wrist sizes. Soft urethane and a flexible fine-resin covering on the underside keep even vigorous arm movements comfortable. Key resin components used in the case, band, and more are made with bio-based resin, a material expected to help reduce environmental impact.
