The Casio Marine Sport Collection Watch AQW-100-1AVEF is a chameleon - wear it on the street, wear it at sea, it's got features for both and it does more than just tell the time.

Need to know the tidal movements? The AQW-100-1AVEF features a Tide Graph display that graphically displays tidal movements based on your current latitude and longitude and the lunitidal interval.

Based on your current latitude and longitude, the AQW-100-1AVEF will also display the moon age and phase on the Moon Age display.

Frequently make international phonecalls? The AQW-100-1AVEF features a second time zone function so you can set the time for two places and call up whichever you need.

No need to fumble around in the dark for a light, the AQW-100-1AVEF features an electro-luminescent backlight and neobrite coating to the hands so you can tell the time in the dimmest of light.

With a stopwatch function, timer and 3 multi-alarms, the AQW-100-1AVEF ensures you always keep track of time.
