I bought one of these because it looked so retro and it was cheap.  Much cheaper than in the stores.  I wish it had four buttons instead of three.  The light button is used to reset the timer and stop watch.  It drains the battery using it.  At first I thought this watch looked so small but I got used to it now.  The band is not long enough.  I don't have super thick wrists but I have the band set close to the max.  The instructions state that this watch is water resistant and not meant for dipping into water.  I've worn this watch swimming many times and it is in good condition.  I even rode on long water slides and dove into water.  I know once I open the back seal to change the battery, the water resistance may not hold.  I'm thinking of using rubber cement to seal it whenever I change the battery.  I love this watch!  I also bought the Electro-Luminescent watch that looks similar but a little thicker.
