FORESEEX Mens Cool Black Metal Alloy Digital LED Wrist Watch with OLED Display and Unique Design OLED Display: display better than LED, pleasant and very readable blue color, easy to read, the letters and numbers on the readout are very clear and bright; the display is bright enough to read in direct sunlight Cool Display and design: when you press the display button; a square blinks then swipes across to show the time or date. Design idea from iron man. Functions: Time and date, weekday, only hours and minutes, no seconds display, 12/24 hours, AM/PM. The weekday will be adjusted automatically when you set the Year, Month, and Day. Weight and Color: the whole watch is made by metal, 150g/5.3 ounce, heavy feel. The color is actually a nice dark metallic bronze color, not entirely black. Power saving design: It doesn't constantly display the time and date so you would have to press the left button to display the date and the right button to display the time. It will stay on for about 5 seconds and then disappear.
