Average Amazon Price: $170 (yes, we may earn a commission on qualifying purchases from our links to Amazon)
Year of first release: 2013

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)
