Amazingly nice!

Amazingly nice!
I just received this watch today and spent some time going through the functions and settings with the manual. Man, this watch is amazingly nice! I can already tell I’m going to wear it WAY more than any of the other watches in my collection regardless of the price of any of them. This thing is just bad ass. Going to have to wait and see how long the battery life lasts. But I love all the functions. I checked the compass and it is perfectly accurate compared to my iPhone compass. Also you can calibrate the thermometer. When you wear the watch on your wrist, your body heat throws off the temperature reading — but you can calibrate it. I kept the watch on my wrist and adjusted the temperature readout to match the temperature of my apartment. I could do that because I have a little thermometer in my apartment so I knew exactly what temperature the watch readout was supposed to be. The manual says you should take temperature readings without wearing the watch to get an accurate reading. But the only time I will ever WANT to take a temperature reading with my watch is WHILE I’m actually wearing it on my wrist, I don’t want to have to take the damn thing off every time. So the calibration feature is great. I just have to remember that now if I take a temperature reading without wearing my watch, it will not be accurate. The overall look of the watch is rugged and gorgeous and sleek all at the same time. The only aesthetic downside is that the black background with gray readout digital displays are hard to read in low light conditions, and completely illegible when it is dark. And the neon illuminator, which is beautiful, does not illuminate the digital displays for some reason. If this watch had regular digital displays with a gray background and black readouts, and also was solar powered, it would literally be the perfect watch. There are solar powered G-Shocks but they are more expensive. Anyway I highly recommend this watch.
Thank you for your feedback
