Today Samsung announced the Gear S2 and Gear S2 Classic, the newest products in their line of smartwatches. The Gear S2 has what Samsung describes as a more minimal and modern design, while the Gear S2 classic uses leather and a black finish in an attempt to appeal to fans of traditional mechanical watches.

In addition to WiFi versions, there's also the Gear S2 3G which includes cellular capabilities to allow the user to make phone calls from their watch. All three models of the Gear S2 are similar, but there are some differences to accommodate visual changes between the Gear S2 and Gear S2 classic, as well as to fit a larger battery in the 3G edition. I've laid out all the known specifications of the Gear S2 in the chart below.

  Samsung Gear S2 and Gear S2 Classic Samsung Gear S2 3G
SoC 1.0GHz Dual Core CPU
Display 1.2" Circular 360x360 SAMOLED (302ppi)
Dimensions Gear S2: 42.3x49.8x11.4mm (47g)
Classic: 39.9x43.6x11.4mm (42g)
44.0 x 51.8 x 13.4mm (51g)
Battery 250 mAh (0.95 Whr) 300 mAh (1.14 Whr)
OS Samsung Tizen
Sensors Accelerometer, Gyroscope, Heart Rate, Ambient Light, Barometer
Connectivity 802.11/b/g/n + BT 4.1, NFC

The Gear S2 is powered by an unnamed dual core SoC with a peak frequency of 1GHz. The circular display has a maximum horizontal and vertical resolution of 360 pixels, which equates to 302 pixels per inch. With Tizen being Samsung's own operating system they can tune the interface to work best with their AMOLED displays to minimize power consumption. Both WiFi versions of the Gear S2 include a 250mAh battery, while the 3G edition increases this to 300mAh, with a corresponding increase in case thickness. According to Samsung, the WiFi only version of the Gear S2 will last between two and three days of typical usage, while the 3G model will last around two days.

The Gear S2 also includes a number of sensors in order to track information pertaining to exercise and fitness. It includes an accelerometer, a gyroscope, a heart rate tracker, an ambient light sensor, and interestingly, a barometer which can be used for tracking elevation by measuring atmospheric pressure. A barometer is a sensor that was notably absent from the Apple Watch, and it could help give Samsung an edge when it comes to the accuracy of their health tracking.

Notably absent from the 3G model is a SIM slot. This is because the Gear S2 makes use of an e-SIM card, an embedded version of the SIM chip current devices use to register and work on mobile networks. It's not clear what implications this will have for carrier compatibility, but it would make sense that support from a carrier would be required in order to use the Gear S2 3G on their network.

Something that differentiates the Gear S2 from Samsung's previous watches are the methods of input that Samsung has included. The bezel around the circular display acts as a rotating input, which the user can use to zoom, scroll, etc. There are also two buttons located next to each other on the right side of the case, which function as home and back buttons respectively. This is again an advantage of Samsung using their own operating system, as they can implement controls that may not work within the control scheme of another operating system like Android Wear.

Naturally, Samsung's Tizen smartwatches don't have access to the application library or functionality that comes with Android Wear. However, a look at Samsung's history with smartwatches makes it clear that they are pushing Tizen as their major wearable platform for their devices rather than Android Wear. It will be interesting to see how this turns out for them. On one hand, they can tune the OS to work seamlessly alongside the hardware. On the other hand, they're limited in terms of third party support from app developers.

The Gear S2, Gear S2 Classic, and Gear S2 3G will be launching in the near future. There's currently no word on pricing, but there is already a commitment from AT&T, Verizon, and T-Mobile USA to sell the 3G version of the watch.

    lol missed the 2 buttons in other articles. like copying the worst thing Apple did wasn't enough.- hope they add pedals next year. Curious what SoC they use, not that it matters much with Samsung prices, that OS and hilarious navigation If i was 15 the design would be ok for the vanilla version.The Classic is a bit too flat. Any clue if it works with a few Samsung phones only? Reply

    For the most part, people have successfully sideloaded any neccessary apps like Svoice onto other android phones. As far as I know, all Gear watches work with all Bluetooth 4.0 LE Android phones with varying amounts of modification. Reply

    Glad they included BT 4.1 in this watch Reply

    This looks like a smart watch going in the right direction.

    1. 2/3 day battery life
    2. Hopefully decent bezel wheel control (like an iPod?) instead of a fiddly crown.
    3. This appears to be a full-circle display! No flat side.
    4. OLED means blacks=no power draw - good design decision

    However Tizen does mean fewer apps to pick from.
    Pricing is key for this device.
    Is it touchscreen as well?

    I actually get 2-3 days out of Gear 2 Neo. I mainly just use it for time. I have the screen black and the numbers gray. I can still read it in full daylight. And I have it set to turn on when I lift my arm up to look at it. If I forget to wear it, it actually lasts like 5 days without charging. How will these charge? Wireless? or similar to the Gear 2, with a charging adapter it plugs into? Reply

    Initially disappointed with my purchase, i have come to grow on the Samsung Galaxy gear S2. The reason for this disappointment was that the amount of apps available in comparison to android wear was lacking. however, the Tizen operating system has been optimised to this, and although there aren't many apps available in comparison to Wear, it is a great watch. Had all the apps on And. wear been available, it would be a clear competitor to Apple Watch.
    Watch is still a little expensive for the functionality of it.
