Tidal wave: The Base Tide Pro Watch by Nixon. The The Base Tide Pro Watch for men from the hip brand Nixon proves that sustainability can look cool and casual. Clear, informative and comfortable are the three inspirations behind the Base Tide Pro. Anything that is not helpful or functional in the water has been left out to make room for useful features and information. Made from recycled ocean plastic, each Nixon watch keeps trash out of the oceans and provides information on a total of 550 beaches around the globe thanks to a pre-programmed tide feature.
