One of the smallest and most compact G-Shocks at the moment. Laconic an-DJ dial with large hands and digital windows contributes to good readability and convenient display of data. The case design is made with notes of “militarism” – dark tones, angular hour markers, “pin” inserts on the case and strap will appeal to the military. Due to the small thickness and width of the body, the AWG-M100 is suitable even for the smallest wrist and will not “stick out” on it, like other shocks. The watch has a fairly advanced filling – solar power and radio time synchronization. The solar battery will allow you to forget about the need to replace the battery after 2-3 years, and the time is automatically synchronized by radio waves with towers located around the world. The basic functionality is also present – a stopwatch, timer, world clock, alarm clock and display backlight.
