I bought this for my husband for when he is working inside hospitals or universities and must know directions when there are no windows to indicate where he might be.  Hopefully, the compass will be helpful at lower levels.  Otherwise, he is very happy with the lightness of it.  Saving his very fine and much more expensive two-tone Swiss Army Watch for more dressy occasions.  He particularly likes the wrist band because of the light weight and the comfort of the black resin strap watch band.  The handy booklet makes it easy to set time, date, temperature, alarm, stop watch, calibrate compass, illuminate face and all kinds of magical things.  I researched for two weeks going from highest prices to lowest prices and settled on this one because of the four and five star reviews by men who know.  My husband is delighted with his new treasure/toy and keeps finding more that can be done with it.  I primarily bought it because he needed a compass.  After purchasing a military compass which is very precise with leveler and sight features, it is also quite heavy but will be utilized.  This watch, however, has the compass which hopefully will serve just as well if not better in the long run.
