Which one fits you
Both need much the same wrist — roughly 44–60mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Epix Pro Gen 2 42mm and Fenix 7S Pro Solar share a near-identical 42mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Epix Pro Gen 2 42mm is thicker than 80% of the 661 42mm watches we hold thickness for, the Fenix 7S Pro Solar than 80% — so both sit higher than their widths suggest.
