History

The original Apple Watch (later called Series 0) was released on April 24, 2015, after years of rumors. While there was a lot of initial hype around it, the third-party watchOS apps were slow to launch due to API limitations. Native apps were available in watchOS 2. The original watch came in 38mm and 42mm sizes.

The Series 2 Watch was released on September 16th, 2016 along with a Series 1 Watch. The Series 2 included the S2 chip, built-in GPS, and water-proof construction. The Series 1 included the S2, but lacked GPS and waterproofing.

The Series 3 Watch was released on September 22, 2017, and it included an LTE option and the S3 chip. The Series 4 Watch was released on September 21, 2018. New hardware included the S4 Chip, Electrical heart sensor w/ ECG app, and larger display (40mm and 44mm sizes).

Apple Watch Series 5 was announced during Apple’s fall event on September 10, 2019. Customers were able to purchase the device later that day, and it was released on September 20. The headline feature for this model was the wearable’s always-on display. The new display always shows the time and complications and is also the first from the company to include a built-in compass.

Apple Watch regains edge in one key way

Apple Watch Ultra blood oxygen sensor

Apple Watch users in the United States are finally seeing Blood Oxygen readings return after nearly a year-long absence. Apple was forced to disable the feature on new Apple Watch hardware sold in the US following a patent dispute with medical technology company Masimo.
