Size, specs & wrist fit compared

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 Fenix 7S Pro Sapphire Solar and Forerunner® 265S share a near-identical 42mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Forerunner® 265S is the slimmer of the two (12.9mm vs 14.1mm), so it slides under a cuff more easily.
On the wrist the Forerunner® 265S feels lighter (39g vs 65g, case only).
Among the 661 42mm watches we hold thickness for, the Fenix 7S Pro Sapphire Solar is thicker than 80% — it will sit high even though the case width reads modest.
The Forerunner® 265S is middle-of-the-pack for thickness among the 648 42mm watches in the database.
The Fenix 7S Pro Sapphire Solar is 0.3mm wider, 0.3mm longer, 1.2mm thicker and 26g heavier than the Forerunner® 265S. Both are circular.
