Nike Ambient Frozen:
The Ambient Frozen looks stylish with its retro analog face, but it also embodies the same durability and digital sophistication as Nike's other premium high-tech watches. Inside the stainless steel locking face is high sensitivity temperature sensor, which features a measurement range from -22 degrees C to +55 degrees C. Accurate to one degree C, you can set the temperature alarm to remind yourself to bundle up--a vital feature when you're climbing into the shady side of a mountain at 11,000 feet. Other functions include a countdown timer, event counter and calendar data.
