The Casio GLX5600-4 wristwatch is a bold, red accessory with a digital display that will enable you to tell the time without struggling to read an analog clock when you're in a rush. The electronic screen also includes the day of the week and date, making it easy to schedule appointments or maintain your calendar. This shock-resistant watch is also extremely durable and won't break easily if it's dropped or treated roughly through everyday wear. Since it's also water-resistant and contains data on the phase of the moon and graphs that detail the tide levels for a specific time and date, it's ideal for surfing.
