Apple Watch is one of the very few v1 products I just never felt the need to upgrade. I tend to always be on the latest generation of everything, but the watch just works fine in it's launch-day v1 state. v2 was underwhelming, and as someone who always has his phone on him, v3 doesn't do much for me.
This isn't a complaint in the least, good to see Apple making products that don't feel old 2.5 years later.
The jump from the v1 watch to the Series 2 isn't a huge win until you use it - Siri is faster, more reliable, and more responsive, other apps are much more useable, battery life is improved, etc etc.
Much of the improvement on series 2 was invisible, but it helps.
