Simple, understated design that suits any occasion For those who wear it for work, we recommend the chic and classic black (all-black) color. For a gift to celebrate entering junior high or high school, blue, which gives a mature impression and is easy to match with uniforms, is a popular color. 2. Durability x Water resistance For those looking for a watch for everyday use to work, expecting durability and water resistance. This is a relatively compact design among the many variations of G-SHOCK, making it easy to use even for those in their 30s. Just wearing it, it charges with solar power and automatically corrects the time at night, making it suitable for everyday use. 3. I want a radio-controlled solar watch that is light to wear! The analog hands are a simple 2-hand type with minute and hour hands. (Seconds display and calendar are digital) This model has a small LCD and case design, so the light feel and compactness of the watch itself are attractive rather than visibility and operability of the functions.
