Editor's Pick: Perfect for fishing or a day at the beach — just lift your wrist to check the tide without pulling out your phone for the app. The moon phase display is also clear, and the backlight is handy for checking the time at night. The battery is said to last up to ten years, so you can wear it daily without worrying about changing it.
