The Samsung Gear S3 is a Tizen-based circular smartwatch manufactured, developed and designed by Samsung Electronics. It was announced on August 31, 2016 and released on November 18, 2016.
There are two models of the Gear S3, Classic and Frontier. The Classic has a silver watch case and black leather band, while the Frontier has a black watch case and rubber band. Both are rated IP68 (water resistant) and have GPS and heart rate monitor sensors. One notable feature is that the bezel ring rotates as part of the user interface, although users can also navigate by swiping the screen and/or using the two buttons on the side.
The Gear S3's successor, the Samsung Galaxy Watch, was released August 9, 2018.
The "LTE" models are further divided into sub-models depending on the target country and Service Provider cellular infrastructure available.
