Women’s G-Shock series for fans of shockproof watches and retro-style. The design of the model resembles vintage music players of the 90s, which also used film media – cassettes. The series is a female analogue of GA-140, only in a reduced form [49 × 45.9 × 15.8 versus 55 × 51.2 × 16.9 mm], but with full preservation of the functionality and strength characteristics of the case. The color scheme includes calm pastel shades that are perfect for sportswear and sneakers. The abundance of digital windows simplifies the display of information, while the classic analog dial fully copes with its function of convenient time display. The watch is equipped with a stopwatch, timer, alarm clock, world clock and perpetual calendar.
