There are different smartwatches available out there now but sometimes you need something specific to cater to your needs. If you're a surfer (professional or otherwise), you might want to check out Nixon's Ultratide Surf Watch. The US$300 watch gets real-time data from Surfline and it'll show you the surf conditions of your favorite spots. It'll even show you 48-hour surf forecasts. To access information on your smartphone, it can be paired via Bluetooth using the Ultratide app. Unfortunately, it's iOS only at the moment. But an Android version is coming soon.
