My EDC watch - Casio PAW 1500 Pathfinder. This unit is packed with information for the person who works and recreates outdoors. This unit is not my first, it replaces my PAG 40 which died recently. The sensors just gave up after 10 years, so I got this one to replace it.
Let's start with time. This unit has local time and a second city available. Mine is set for Chicago, and "Zulu" - UTC time. When I operate as a ham, I don't have to constantly think the difference, but just glance at it. One less thing to worry about while on the air. Stopwatch, when you need one, this has it.
Beyond this - is a Barometer with graph for the past 12 hours. Nice to know what is going on with the weather. Having taken a weather course I can predict the weather better than the TV goof. This is one of the leading ways to tell what is going on. It also has a digital compass, which gives one the wind direction and is good for finding one's way. Ever find yourself off on a detour and can't figure which way is back to the office after being turned around several times? This can give you an idea at the next crossroads.
The Moon Phase is neat to watch, and it does calculate the exact moon age. If you are into this, like I am, this is a neat feature. The tide graph really doesn't do much in the Great Lakes area, but is fun to watch.
Five alarms, and the hourly chime round this unit's output.
Now what is neat is it is a "tough solar" unit. This means it charges the battery while you are out. No more dead batteries. Another really neat thing is the "atomic clock". At midnight it picks up the Fort Collins time signal and sets the watch to the correct time. Now you know that you have the exact time.
All in all, a versatile unit. Waterproof to 200 meters, it is overall winner for one on the go and needing data as to how the weather is doing, where you are, and what is the exact time.
