    This G-SHOCK Gravitymaster is a real beast on the wrist. You can tell right away that this is a watch built for tough jobs—the carbon case makes a great impression; it’s incredibly sturdy, yet lighter than I expected given its size. The design with turquoise accents on the black dial looks very modern and professional, definitely standing out from other models. From a technological standpoint, it’s perfect for me. Tough Solar solves the battery problem, and Bluetooth allows for instant time synchronization and access to features via a phone app. The Flight Log feature is very useful, allowing you to record your location, which is a great addition for people who enjoy traveling and logging routes. The Super Illuminator backlight and Neobrite coating make reading the time at night a breeze. It’s a watch that not only looks great but gives you the feeling that it will survive any adventure.
