Quick Take: If you're a surfer, there's nothing worse than pulling up to the beach to find that the tide has ruined the waves. Now, you can know before you go with the Rip Curl Method Oceantide watch. Along with all the functions of a regular watch, including an alarm, a calendar, a stopwatch, and a backlight, this water-resistant device provides digital tide readings, which you can program to 1,000 different beaches. Plus, with the Rip Curl's cool looks, you can go straight from the beach to the luau in style. At $100, this nifty accessory costs a little more than a typical watch, but it will help surfers catch plenty of waves.
