Combining stellar outdoor features with outstanding precision, this Casio G-Shock Gulfmaster chronograph is built to withstand the harshest environments. An ocean concept timepiece inspired by the image of a man tough enough to master the wild seas, the Gulfmaster is fastened with a strong and durable black resin strap and features a 44.9mm black stainless steel and resin case with a blue bezel and the signature shock resistant construction which protects against impact and vibration and puts the G-Shock collection head-and-shoulders above the rest. Beneath the scratch resistant sapphire crystal, the black dial features hour markers which are coated with Neobrite to provide long-term illumination in the dark after only a short exposure to light, one sub-dial and a digital display, and is illuminated by an Auto LED which is activated when the watch is tilted towards you. Very easy to use, the Gulfmaster is equipped with a Smart Access crown which allows intuitive control of its array of advanced functions such as an altimeter, thermometer, 1/100th second stopwatch, tide graph display, 5 daily alarms, countdown timer, world time in 29 time zones, barometer and digital compass. Water resistant to 200m, this high-tech watch is powered by a Tough Solar movement which generates energy even from small amounts of fluorescent lighting and features multi band 6 radio controlled technology to ensure that the exact time is displayed across Europe. Designed to accompany you on all of your adventures, this remarkable Gulfmaster is built to help you conquer the outdoors. GWN-1000B-1BER
