The Fenix 9 lists up to 29 days of battery on the 51 mm case; the Forerunner's label reads up to ~15 days (approximate). The Fenix 9 offers three case sizes against one, 10ATM water resistance with a 40-meter diving rating and a military durability rating against 5ATM. It also lists a ~2,000-nit display (approximate), a figure the Forerunner does not list at all, and a sleep apnea sensor the Forerunner does not list. The Fenix line offers an LTE option on the Pro variant; the Forerunner 970 has no cellular option. The Forerunner's answer is focus: one 47 mm running case with a titanium bezel.
