In a speed test video by “MacRumors”, they performed an interesting speed test on the Apple Watch (1st generation) vs the Apple Watch Series 1 vs Apple Watch Series 2 vs Apple Watch Series 3 and Apple Watch Series 4.
The Apple Watch Series 4 launched last week and features an all-new edge to edge display, louder speakers, a new Electrical Heart Sensor with EKG/ECG ability, and more importantly an all-new Apple Watch S4 SiP (System in a package), this is the first 64-bit Apple Watch processor, unlike the Apple Watch Series 3 and earlier, which feature an older 32-bit architecture. This type of processor addresses memory that is of the 32-bit register, which makes overall system performance and general response slower and more of a struggle. 64-bit was first launched in the iPhone 5s in 2013 and with iOS 7, but since smartwatches use small logic boards, which is a remarkable feat of engineering, we see slower developments with processor improvements and general improvements.
Apple recently dropped the Apple Watch (1st generation) from watchOS 5, stating that “watchOS 5 is not compatible with the first-generation Apple Watch.”, which is most likely because the Apple Watch (1st generation) was slow from watchOS 1.0, and on, and everything was a drag.
We see massive performance improvements in this video, most likely due to the 64-bit design, apps launch faster, and are more responsive, and things like Siri and scrolling is much smoother. The Apple Watch Series 3 was never slow, however the new Apple Watch Series 4 makes it look slow, and makes the Series 2 look really slow, since it has an S2 processor.
To clear things up, there is a lot of confusion between the Apple Watch (1st generation) and the Apple Watch Series 1. The Series 1 was launched in 2016, alongside the iPhone 7 and iPhone 7 Plus at the fall 2016 iPhone Media Event, however Apple also launched a Series 2 model at the time, which features waterproofing and a brighter OLED screen. Apple dropped the 1st generation in 2016, and replaced it with a “Series 1”, with an improved S2 processor, so it  “is just as fast and snappy as Series 2”
