The battery onthis one is good for five years

The battery onthis one is good for five years, so even if you forget it in a drawer,you're unlikely to need to reset it!200m water resistant (about 650 feet). Several people use this watch for SCUBAdiving; it's more than enough for any use you're likely to have.Travel friendly. Unlike most watches, you can change thehour without stopping the watch. This is fantastic when traveling. Youpull out the crown, press the button while rotating the stem, and the houradvances. I used this when going from the west coast to SouthAmerica, and I can testify to its usefulness. With other watches,more than once I've set the local time wrong due to jet lag haze. Alsonice for accuracy fans, since the seconds and minutes are not affected.Power saving modes. This adds some personality to the watch, and makes itfun to interact with. After a minute or two of darkness, the secondhand stops at 12 and stays there until light returns. Meanwhile,the minute and hour hands continue to display the correct time. If light remains off for three days, allthe hands stop, only to spin to the correct time when you take it outof the drawer. These makes the watch seem a bit more alive -- more thanonce, I extend my arm and watched the second hand wake up from falling asleep undermy coat. The watch will warn you if the battery was depleted far enough that it lost time.Luminosity. The face has large, clear markers with Luminova onthem, *** it easy to read at night. The second hand is notlumed, instead having a painted red tip.
