How is the epix Pro Sapphire different from the standard epix Pro?

The Sapphire Edition adds a scratch-resistant sapphire lens over the AMOLED display. The rest of the hardware and software, including the flashlight, maps and training metrics, is the same.

Is it worth it over the Forerunner 965?

The Forerunner 965 is lighter and has a similar AMOLED screen and mapping. The epix Pro Sapphire adds sapphire glass, a built-in flashlight and a tougher case, which matter most to athletes who are hard on their watches.

How long does the battery last?

Garmin rates it for days of smartwatch use, with always-on display and heavy GPS activity cutting that significantly. Expect to charge weekly in normal use and more often during long GPS sessions.

Does it work with a chest strap and bike sensors?

Yes. It pairs with ANT+ and Bluetooth sensors, including heart-rate straps, power meters, speed and cadence sensors, and it supports Garmin's running dynamics with a compatible strap.
