"Simple and easy to use"...Timex Expedition. Several models available. Simple, and they work. All the other bells and whistles like barometer, etc. are really not all that useful in the end. My day to day watch is a titanium Citizen Ecodrive. Been with me 5 years without a battery change. But....too expensive for hiking. I take the Timex.
