Fitbit smartwatch

Following on its acquisition of Pebble, and the company's announcement just this week that it would be developing an app store, Fitbit has announced another smartwatch acquisition: Vector, a year-old Romanian startup that boasts a smartwatch with a 30-day battery life.

When Fitbit bought Pebble at the end of last year, the evidence seemed against Fitbit branching into real smartwatches: The company explicitly declined to buy Pebble's hardware business or hire any members of Pebble's hardware team.
