Beautiful watch can be worn hiking, rafting, exercising (although a bit uncomfortable while running), scuba diving, skiing, or dressing up!  This watch looks formal, but is very tough.  I wear it everywhere while doing everything.  I've dropped a hammer on it, I've scraped it up against wood and rocks.  It's been buried in sand.  There's nothing this watch can't handle - and I can't even see any scratches on it (i'm not kidding)!  I've got 2 'nice' watches sitting at home which I broke (Swiss, Fossil) - one of them fell off the counter and the other just stopped working.  This G-Shock looks the same as all watches, cost the same price (probably cheaper), and survives much more than those things ever could. Here are the features of the watch:

Atomic Clock setting: I never have to set the time.  EVER.  This atomic clock searches for a signal at the same time every day to ensure correct time setting - even knows when DST is on or off.  There is even a signal indicator so that wherever you set it when you come home, you know it has a good (or bad) signal and will be able to set itself come sync time.  You never have to set a THING!

Battery indicator: This thing relies on solar power. It sat in a dark gift box for 2 months and when I opened it the battery indicator was at medium.  After setting it on a window sill for a day (in Michigan in DECEMBER, where days are only something like 8 hrs long), the battery was at full - and hasn't gone down to medium ever since.

Auto-off and Auto-light: When it's too dark for too long, the display actually turns off to conserve battery.  When you press a button, it turns back on for a minute or so.  It can also sense tilt, so when you bring the watch up to an angle to check the time, the light comes on automatically (feature can be turned on/off)!  This is a great feature.  Just the natural motion of you checking your watch makes the light go on.  I always find myself tilting my watch up and seeing the indigo backlight come on while in the movie theater and then giggling - it's almost as if the watch is reading my mind by knowing that I want to see the time and it's dark!  This feature is very smart, as it will actually NOT work when it's light out to conserve battery - another thing you never have to worry about!

Mode1 - time: your standard time display - hr/min/sec, date, day.  You can choose between 12hr and 24hr time.

Mode2 - alternate time zone: useful if you travel a lot.  It displays the alternate time zone in big numbers, and your default time zone is in small numbers at the bottom of the display - so you always know the time difference in case you want to call home!

Mode3 - Time record: I haven't found a use for this yet.  At any time throughout the day, you can press the "time memo" button.  This button records the current time/date down to the second and then stores it (in mode3).  You can then switch to mode3 and review all your recorded times (up to 30 of them).  I have not found a use for it yet.  I guess if you wanted to keep track of when the sun sets every day or at what time you arrived to work - this would be a useful function for you.

Mode4 - alarms: this thing has 5 separate alarms!  This is very useful to me, especially since I like to keep an eating schedule (if you've ever tried Eating for Life, then you know what I mean).  There are alarms 1,2,3,4, and SNZ.  The SNZ is my morning alarm clock.  It goes off every 5 minutes for a duration of 30 minutes.  You can press a button to "snooze" the timer (just like an alarm clock).  Then the rest of the alarms are set for when I need to eat.  It works perfectly if you need daily reminders for pills, injections, etc.

Mode5 - stopwatch: your standard stopwatch function.  It can be stopped so you can write down a recorded time while the stopwatch is actually still operating, then once you recorded the time you can go back to the stopwatch and stop it again for record if you need to.  The watch itself does not record these times, you would have to write it down.  One feature I like is the fact it displays the current time on the bottom of the display so you don't have to ever switch back and forth.
