The IFA 2015 brought in its folds a slew of new smartwatches from several OEMs which are eyeing for top honors in the burgeoning wearable space.
We take a look at some of the top contenders for the best smartwatches of the near term and compare the Samsung Gear S2, Moto 360 2, Asus ZenWatch 2 and the Huawei Watch - how they stack up against each other.
The Moto 360 2 sports a round dial and is available in two sizes for men 42mm and 46mm diameters, which translates into a 1.37-inch (360 x 325) and 1.56-inch (360 x 330) display, respectively. The pixel density for the 42mm and 46mm versions is 263ppi and 233ppi, respectively.
Both the Motorola smartwatches have a Backlit LCD screen with Corning Gorilla Glass 3.
The Samsung Gear S2, on the other hand, sports a smaller 1.2-inch Full Circular AMOLED display. However, at 360 x 360, the pixel resolution is higher when compared to the Moto 360 II offerings. The 306ppi pixel density of the Samsung offering also easily trumps that of its rivals.
The smartwatch has the same thickness as that of the Moto 360 2 i.e. 11.4mm and weighs between 42gms to 51gms depending on the model.
The Asus ZenWatch 2 has a rectangular dial when compared to the other two wearables and sports a 1.63-inch (320 x 320) AMOLED screen with Gorilla Glass 3. The 278ppi pixel density is lower than that of Samsung's offering but higher than that offered by the Moto 360 II.
The smaller model has a 1.45-inch (280 x 280) AMOLED screen with Gorilla Glass 3 and 273ppi. The thickness of this model is the same as the Moto 360 II and the Gear S2. The bigger model; however, is sleeker and is just 10.9mm thin.
The Huawei Watch is circular as well and has a 1.4-inch AMOLED screen - which is made of Sapphire crystal - with the highest pixel resolution out of all the watches i.e. 400 x 400. The pixel density of the smartwatch at 286ppi is the second best of the lot. The wearable is 11.3mm thick making it the second most sleek smartwatch of the four.
