Garmin Fenix 7S Pro Solar Edition vs Fenix 7X Pro Solar Edition
Size, specs & wrist fit compared
Which one fits you
Under 18 cm (7.1 in) round, the 51mm's lugs overhang and the 42mm's do not; the 42mm fills the wrist at 16–17.5 cm, the 51mm at 19 cm and up.
What else differs
- Screen: the 51mm has the larger screen, 1.4 in across against 1.2 in on the 42mm.
- Battery: 28 days for the 51mm against 11 days for the 42mm in everyday use; 3.7 days for the 51mm against 37 hours for the 42mm with GPS on.
Among the 52 smartwatches 51mm across that we hold thickness for, the Fenix 7X Pro Solar Edition is thinner than 87%, so it wears flatter than its width suggests.
The Fenix 7X Pro Solar Edition is 9mm wider, 0.8mm thicker and 33g heavier than the Fenix 7S Pro Solar Edition.
