Our Verdict

Garmin Instinct 3 45 mm AMOLED is the better fit if this comparison is really about training, outdoor navigation, water resistance, and rugged health tracking. It gives you built-in GPS, multi-band positioning, Garmin Pay, Pulse Ox, a barometric altimeter, a flashlight, and stronger water resistance. Pebble Time 2 is the better fit if you want a simpler smartwatch with e-paper, buttons, PebbleOS, old Pebble watchfaces, a lower price, and a lighter body. It is not trying to be a Garmin-style sports watch, and Pebble says that clearly. Choose Garmin for fitness and adventure depth; choose Pebble for a calmer, hackable, nostalgic everyday smartwatch.
