by the way im 14

the first one l reckon. its shiny =] haha

The Avocado. It is got the easy to view tide graph and the black band is less likely to attract sea life. Looks cooler too (if that matters). l do not know how much the surf brand watches cost, but a few years back, l bought a Casio tide watch, and it is been great. It cost about 60 bucks. It came preprogrammed with tides, but l had to enter the longitude and latitude for my break. http://calibex.com/casio-tide-watch?nxtg=df4a0a240513-E2CFB981C2D52BC5

Avacado, you do not want to attract those shark with that shiny one.

if you are surfing in it, then l would get the avacado. it has a tide chart on it so you can see what time to go surfing. plus when you are out in the water, the beirut will attract things like sharks and fish and birds because it is shiny. hope this helps.
