Review on Casio AE-1500WHX-1A by Petar Vachkov

Excellent timepiece; its directional indicators actually work (a rarity among Chinese wristwatches). The diode backlight is quite effective; it illuminates the screen for three seconds, and nothing is obscured. Ten-year battery life You may toggle between 24 and 12 hour modes with the button on the lower right. Hourly. Simply pressing this button will toggle the time display from 12 to 24 hours (no additional settings are required).
