I have a Moto 360 that I like. My best friend has a Fossil smart watch that he really likes. What kind of alarm are you looking for? Something to wake you up in the morning? Or just something to alert you during the day? If it's too wake you up, you're gonna have a hard time finding one with enough battery life. They lose power really quickly. Getting more than about 10-16 hours of use is hard. So you might be able to charge it and wear it overnight, but them out would die during the day. Pebble makes a version that has a long battery life, but it doesn't have ass many features as other watches. How this helps a little.
