Garmin Fenix 5 vs Forerunner 570 47mm
Size, specs & wrist fit compared
Which one fits you
Both need much the same wrist: neither overhangs from 16.5 cm (6.5 in) round, and both are in their sweet spot around 17.5–19.5 cm. Wrist size will not decide between these two.
What else differs
- Screen: the Forerunner 570 47mm has the larger screen, 1.4 in across against 1.2 in on the Fenix 5.
- Battery: 14 days for the Fenix 5 against 11 days for the Forerunner 570 47mm in everyday use; 24 hours for the Fenix 5 against 18 hours for the Forerunner 570 47mm with GPS on.
The Fenix 5 and Forerunner 570 47mm share a near-identical 47mm case, so on the wrist the difference is thickness and weight.
2.6mm thinner, the Forerunner 570 47mm is the one that slides under a shirt cuff.
Among the 79 smartwatches 47mm across that we hold thickness for, the Fenix 5 is thicker than 89%, so it sits higher on the wrist than most of its size.
The Fenix 5 is 2.6mm thicker and 35g heavier than the Forerunner 570 47mm.
