Samsung Gear S2 / S2 3G / S2 classic

Request Quote

The Gear S2 is radically different from any other wearable Samsung has put out. There is, of course, the obvious fact that it is the first to utilize a round form-factor, but that is just the tip of the iceberg. The new Gear is yet another radical development in Samsung’s wearable family that has been frantically moving towards and then away from standardization and the Android Wear OS. While still relying on the custom Tizen platform, the Gear S2 now looks to be more in-line with today’s smartwatch trends, as set by Google and Apple. Samsung might have finally found a proper course of development to stay in tune with the general flow, while still working on its own vision and delivering a fresh and alternative, yet somehow familiar experience.

The Gear S2 is the first milestone on this new path and it is eerily familiar and surprisingly different all at the same time. One important note to make, before we dig in any further, is that the Gear S2 actually has three distinct variants. The Gear S2 and S2 Classic share the same hardware, but have quite a few design differences. 

First things first, let’s talk about version and how they differ. There are three varieties of Samsung’s new wearable. The plain Gear S2, features a fine and uniform finish all around and comes with a silicon band with a proprietary connector. In contrast, there is the Gear S2 Classic, which has a lightly different wheel and uses a standard strap that you can easily swap for an after-market solution.
Last, but not least, there is the 3G model Gear S2, it looks practically identical to the plain one, but is overall a bit bigger, bulkier and heavier. It complements the wearable line in much the same way LG Watch Urbane LTE does, but should enjoy broader availability. The name of the watch itself definitely suggests some relation to the Gear S, but apart from the Tizen-based OS, the two devices actually have little in common. As already mentioned, it seems Samsung has decided to draw from its abundant experience in the wearable field and start working towards similar goals as most of its competitors, which are now shaping to be the new direction of the niche and possible, the future of smartwatches as a whole.

The Gear S2 3G, on the other hand offers 3G connectivity and it is a bit thicker and heavier than its siblings and comes with a different chipset. Here is a quick rundown of its features:

Design and build quality:
There definitely seem to be two schools of design thought in today’s smart wearable industry. On the one hand we have the more techy approach, usually associated with fitness trackers, but also some watches, where it is plainly obvious that the gadget you are wearing is indeed a futuristic piece of tech. A good example would be the Gear S or even the Apple Watch. On the polar opposite, there is the push to seamlessly mold technology into the existing watch design. Make a product that simply upgrades the watch experience, rather than reinventing it completely, like the LG Watch Urbane or say, the Huawei watch. 

Hardware overview
Samsung has always kept back from using standardized hardware that comes as a requirement for Android Wear OS. Even with the newly found similarities, the Korean giant still remains quite different from the smartwatch crowd in terms of hardware and software.

Samsung has opted for a very nice display on the Gear S2. The round panel is of the Super AMOLED variety, which definitely provides richer colors than the widely-employed P-OLED displays of the competition. At 1.2 inches, the screen is slightly smaller than say what LG, Motorola or Huawei has to offer. However, with a resolution of 360 x 360 pixels, the Gear S2 is second only to the Huawei Watch and the new LG Watch Urbane 2nd Edition when it comes to picture detail. With the lower screen, pixel density works out to 302 ppi, quite impressive for a watch.
