역사적 배경

Apple Watch Series 3 was introduced on September 12, 2017, and was released alongside the iPhone 8 on September 22, 2017. The main new feature is built-in LTE cellular connectivity and offers both voice and data communication, including out-of-the-box Apple Music streaming. Antenna functionality (receiving and transmitting elements for LTE and UMTS) is part of the display and the watch features an electronic SIM (eSIM), 1% the size of a standard SIM card, and shares the same mobile number as the user's iPhone. Apple claims 18 hours of battery life. It has a dual-core Apple S3 processor, which Apple claims is 70% faster than the S2. The cellular-capable watch has a red digital crown but the Series 3 device is also available in a non-LTE version. Siri is able to speak on Apple Watch Series 3 due to the increased processing speed of the Watch. On launch, GPS + Cellular models were available in Australia, Canada, China, France, Germany, Japan, Puerto Rico, Switzerland, the United Kingdom, and the United States.
