The third-generation Apple Watch, introduced in September 2017 as the Series 3, brought significant upgrades that further expanded its capabilities, especially for fitness enthusiasts and those seeking greater independence from the iPhone. One of the standout features was the inclusion of cellular connectivity, allowing users to make calls, send messages, and stream music directly from their watch without needing to be tethered to an iPhone. This model also featured a faster dual-core processor, making the device more responsive and efficient, as well as a barometric altimeter for tracking elevation during outdoor activities like hiking and skiing. The Series 3 continued to focus on health and fitness with heart rate monitoring, GPS, and swim-proof capabilities, all housed in a sleek, durable design. With cellular options and improved performance, the Apple Watch Series 3 marked a major leap forward in the evolution of wearable technology, offering more freedom and functionality than ever before.
