Man get her a gshock... PX carries only few variations of gshock. But you can buy it in many different shape and sizes on the web so she will have one of the kind watch. They are strong, multi function, durable and nice looking. With their illumination they can be read in the dark easily.

If she doesn't need a multifunction go with Luminox.

Drop the sunnto line. Too complicated to use with short battery life.
