very large watch. fairly easy to navigate once you practice. temp gauge not so accurate and in the instruction booklet  it says to wear it over a jacket or on your pack (well then what's the point of a wrist watch) but the body raises the temperature...so that's not so accurate. i'm not sure how to read this compass so i'm not sure if i calibrated it correctly. i was able to use the chrono and review easily. i love the orange color. it has two clocks analog and digital and you can choose what other info you want to display. baro, elevation or date/day. so i guess this watch can predict weather patterns....that is if you set it correctly and back to the temp issue not sure how that affects it's forecasting ability. overall, i like it....and i'm a gurl!
