It's been more than two years since Samsung launched its first fitness tracker, the Gear Fit. On Thursday, the South Korean technology giant unveiled the follow-up, predictably called the Gear Fit 2.

Samsung's new tracker features a 1.5-inch curved Super AMOLED display (432 x 216 pixels, 322 PPI) powered by a dual-core Exynos 3250 SoC alongside 512MB of RAM. Other amenities include 4GB of onboard storage, Bluetooth, integrated GPS, a heart rate sensor and automatic exercise tracking.

It packs a 200mAh battery that Samsung says should last around three or four days, depending on usage, with recharging taking place via proprietary charging cradle, we're told. The wrist strap isn't interchangeable although you can select from different sizes at the time of purchase.

The wearable also carries an IP68 rating meaning you won't need to take it off to shower although you probably won't want to go for a swim with it on. It runs Tizen, Samsung's home grown operating system. Like the Pebble 2 and Time 2, Samsung's new wearable will include a dedicated Spotify app for music streaming.

One of the tracker's shortcomings is the fact that it won't connect to iPhones. As The Washington Post notes, it will link with all Android phones - not just Samsung handsets.

Samsung will begin accepting pre-orders for the $179 Gear Fit 2 in black, blue and pink on June 3. Launch takes place a week later on June 10.
