I have an opportunity to get AW Series 1 38 or 42mm for $100 off retail (thru my insurance plan) so this means, I can buy AW S1 42mm for $179. No discount for S3 unfortunately. Because of that, I am comparing $179 vs $359 (S3 aluminum 42mm). I care less about GPS, water resistance or LTE or Siri. The only concern I have is the performance of stock apps on S1 vs S3. It seams to me that paying double for %20 performance increase would be insanity in my case? Am I missing something? Is S1 still a good buy given my situation? Any issues running watchOS4 on S1?
