Apple S1

It uses a customized application processor that together with memory, storage and support processors for wireless connectivity, sensors and I/O constitute a complete computer in a single package. This package is filled with resin for durability.{{cite web|url=https://www.apple.com/watch/technology/|title=Apple.com - Apple Watch - Technology|work=Apple|access-date=8 October 2014|archive-date=9 September 2014|archive-url=https://web.archive.org/web/20140909204623/http://www.apple.com/watch/technology/|url-status=live}}

The SiP in Apple Watch Series 1 is called S1P and looks superficially identical to the S1, but in reality is an S2 minus the on-chip GPS functionality. It contains the same dual-core CPU with the same new GPU capabilities as the S2 making it about 50% faster than the S1.{{Cite web |url=http://ifixit.org/blog/8439/apple-watch-series-1/ |title=We Just Took Apart the Apple Watch Series 1—Here's What We Found Out |access-date=13 October 2016 |archive-date=24 January 2018 |archive-url=https://web.archive.org/web/20180124142636/https://ifixit.org/blog/8439/apple-watch-series-1/ |url-status=live }}{{Cite web |url=https://www.apple.com/pr/library/2016/09/07Apple-Introduces-Apple-Watch-Series-2-The-Ultimate-Device-For-A-Healthy-Life.html |title=Apple Introduces Apple Watch Series 2, The Ultimate Device For A Healthy Life |access-date=8 September 2017 |archive-date=14 April 2017 |archive-url=https://web.archive.org/web/20170414125959/https://www.apple.com/pr/library/2016/09/07Apple-Introduces-Apple-Watch-Series-2-The-Ultimate-Device-For-A-Healthy-Life.html |url-status=live }}

The S1 was announced on 9 September 2014 as part of the "Wish we could say more" event.

The S1P was announced on 7 September 2016 as part of the "See you on the 7th" event.

The S1 made its first appearance within the Apple Watch, which arrived in April 2015.{{Cite web |url=http://www.macrumors.com/2015/01/27/tim-cook-apple-watch-on-schedule-to-ship-in-april/ |title=Tim Cook: Apple Watch on Schedule to Ship in April |access-date=30 January 2015 |archive-date=4 April 2015 |archive-url=https://web.archive.org/web/20150404001009/http://www.macrumors.com/2015/01/27/tim-cook-apple-watch-on-schedule-to-ship-in-april/ |url-status=live }} The S1 was discontinued with the launch of Apple Watch Series 1, containing the S1P.

The S1P was released with the Apple Watch Series 1 on 16 September 2016.
