I upgraded from a Fenix 5 Sapphire watch and I'll tell you this is an awesome watch. The AMOLED display has vibrant colors and the battery life is plenty for almost any endurance activity you can think of. I really enjoy the *on gesture* on display and the brief morning report. The HR sensor is much improved and it tracks right on with the HRM Pro plus strap. It is pricey, but you get what you pay for. I really enjoy it.
