Side-by-side comparison of specifications and features
Compare visual case presence and physical footprint on one shared wrist. Measure your top-down wrist width for a stronger result; lug-to-lug is used when the catalog has it.
Medium (6.7″)
Estimated top width: 56.7 mm
Preliminary range: 54.7–61.8 mm.
Watch A

Proportional guide only: visual presence and physical footprint do not predict comfort. Weight, thickness, caseback shape, rigid lugs, strap stiffness, wrist-bone prominence, wearing tension, bezel design, and case curvature change how a watch actually wears.

Seiko SKX009 — it is 46mm lug-to-lug versus 48mm, and lug-to-lug is what decides whether a watch overhangs a smaller wrist.
They are rated the same, so water resistance will not decide this. Choose on strap material and how much you mind scratching the case.
Seiko SKX009 is the value pick at roughly $175 less. Pay more only if a specific difference above matters to you — otherwise the cheaper one is the smarter buy. Confirm live listings, since marketplace pricing moves.
