Pebble is back and is betting that a 30-day battery life can shake up the smartwatch market dominated by Apple Watch.

After a rollercoaster rise and decline that started with Kickstarter and ended with Fitbit kicking the Pebble brand to the curb, co-founder Eric Migicovsky launches new 'Pebble-like' devices.

The Core 2 Duo and Core Time 2 are arriving in July and December, and I love that they'll last forever on a charge.
