for me applecare was one the best decisions when getting the watch. I bought gen 0 Stainless steel during black friday 2016 (from B&H bought for $269), added applecare within few days. When i began to have trouble with it, around april-may 2017 apple replaced my watch with Series 2 (mind you in stores it was $599 - 42mm). When I went to the store to exchange my gen 0 for series 2 they also extended my applecare (which is set to expire in summer of 2019). So yea, I think its worth it 100%
