The best and worst smart watches rated by Consumer Reports

NEW YORK CITY (WABC) -- We all have smartphones, but are all you gadget lovers ready for the smartwatch?

Consumer Reports has just finished testing the latest watches to help make buying one a little easier.

Smartwatches come in all shapes, sizes and prices and offer to count your steps, check your heart rate and display all your notifications.

Consumer Reports has rated more than a dozen watches, putting them through a variety of tests.

The lab checked the durability of the cover glass by scratching it with picks of increasing hardness. They also tested heart rate accuracy by comparing watches to the lab's highest rated heart rate monitor, and testers assessed water resistance by putting watches in a pressurized tank.

The $175 Sony SmartWatch 3 failed this test and landed at the bottom of Consumer Reports' ratings.

Apple Watch is at the top of the ratings, but costs $550 and up.

"The face doesn't scratch very easily," Consumer Reports' Kerry Allen said. "And Apple Watch has caught up with Android Wear and Pebble to allow apps to be developed by third parties."

That means plenty of options like Fantastical, a calendar app, and OmniFocus, a personal-organizer app.

A good, less expensive choice is the $130 Asus ZenWatch 2. Unlike Apple, you can use it with a phone that runs on iOS or Android.

Another option is the $350 Samsung Gear S2, which offers 3G so you don't have to stay tethered to your phone.
