Nominations: best design, best resistance
The most distinctive specs:
– 200-meter water resistance (good for swimming but not for deep diving)
– Digital compass (measures and displays direction as one of 16 points)
– Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
– Neon Illuminator (Illuminating the display causes the face, and hour and minute hands to glow with neon color, which looks great late on a dark outdoor night)
