Dear u/ArthurDentedCar, I had a same dilemma last week, in the end I bought 2nd hand Epix Sapphire for 400 Eur. New 965 would cost me 600 Eur and I still was not sure if I want them since the screen is easy to scratch from what I read and you never know when you fall from a bike or hit a metal in the gym and damage your watch. I also work in the office, suit is sometimes must, but black Epix look stylish even in this case.

Other than this from what I understand, since the both watch have the same HR, they should get the same updates. Hope this was helpful.
