Which one fits you

Under 18 cm (7.1 in) round, the 51mm's lugs overhang and the 47mm's do not; the 47mm fills the wrist at 17.5–19.5 cm, the 51mm at 19 cm and up.

What else differs

  • Screen: the 51mm has the larger screen, 1.4 in across against 1.3 in on the 47mm.
  • Battery: 37 days for the 51mm against 22 days for the 47mm in everyday use; 12.0 days for the 47mm against 5.1 days for the 51mm with GPS on.

Among the 52 smartwatches 51mm across that we hold thickness for, the Fenix 7X Solar is thinner than 87%, so it wears flatter than its width suggests.

The Fenix 7X Solar is 4mm wider, 0.4mm thicker and 17g heavier than the Fenix 7 Solar.
