Which one fits you
Both need much the same wrist — roughly 54–73mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Fenix 7X Pro Sapphire Solar and Fenix 7X Pro Solar share a near-identical 51mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Fenix 7X Pro Sapphire Solar feels lighter (89g vs 96g, case only).
The Fenix 7X Pro Sapphire Solar is thinner than 90% of the 48 51mm watches we hold thickness for, the Fenix 7X Pro Solar than 90% — so both wear flatter than their widths suggest.
The Fenix 7X Pro Sapphire Solar is 7g lighter than the Fenix 7X Pro Solar. Both are circular.
