I must say this is a great watch. I recently bought it from amazon and arrived in perfect condition. I live in Venezuela and the "sunrise/sunset" function amazed me! My city (Maracaibo) appears in the watch, just like many other places around the world

I tested the altimeter function using the elevator where i live and once i gave a referencial altitude (4meter above sea-level) the altitude began to raise. I live in 7th floor and gave me a read of 25 meters

Temperature function, performed flawlessly once you remove it from your wrist

Compass, same way. Once you calibrate it by rotating the clock a couple of times and that's it

Barometer pretty accurate

Bottom of the line, it's the perfect device for outdoors activity and very stylish for everyday use.
