The new Samsung Gear S2 is indeed round, the bezel rotates like a little steering wheel to navigate apps, and one version of the watch has its own embedded 3G e-SIM card that can make calls and slurp data without a phone.
There’s also another version of the Gear S2 without that 3G connectivity. Both options include Wi-Fi, Bluetooth 4.1, and NFC, and the ability to use it as a wrist-mounted credit card via Samsung Pay support.
Perhaps the most impressive part of the new watch is the dimensions of its face. With a 1.2-inch-diameter AMOLED display—one with a befitting resolution of 360×360 pixels—the screen is significantly smaller than that of the Moto 360. It’s more along the size of the LG G Watch R, which should give it a bit more of a “normal watch” size and look. And both versions of the watch have an IP68 dust- and water-resistance rating, which mean they should be fine to wear in the shower.
That said, the non-3G version of the watch is 11.5mm thick, which is the same depth as the Moto 360 and a millimeter thicker than the Apple Watch. If you want the 3G version, that depth chunks up to 13.4mm. Both versions of the watch have a display with a pixel density of 302ppi, which is a bit shy of that of the Apple Watch (326ppi).
