Just recently, Apple added the first-generation Apple Watch (“Series 0”) to its obsolete product list. At the same time, Apple also added the Apple Watch Series 1 to its vintage product list. As a reminder, a product from Apple is declared “vintage” when it’s five years since Apple stopped selling that product.
The Apple Watch Series 1 was introduced alongside the Series 2 back in September 2016 as a lower-cost option. The Series 1 was simply identical to the original “Series 0” model, except it had the SiP S1 that offered the same performance improvements as the higher-end Series 2 but without the GPS. The Series 1 was offered in silver, space gray, yellow gold, and rose gold aluminum case options.
The following year, when Apple introduced the Series 3, Apple discontinued the Series 2 but kept the Series 1 in the lineup. However, both the yellow and rose gold options were discontinued as well. The Series 1 went on sale until Apple introduced the redesigned Series 4 with the Series 3 remaining in the lineup as the more affordable option. The Series 1 would continue to receive software updates until September 2020, with watchOS 6.3.2 being the final software update.
Nowadays, Apple sells the Apple Watch SE, which is considered the spiritual successor of the Apple Watch Series 1.
