Identity
The Seiko 5 Sports SKX Redux SRPL85K1 is a 42.5 mm automatic sports watch built for daily wear and recreational water use. Its stainless steel case and bracelet suit buyers who want a single mechanical timepiece that transitions from desk to dive without a battery change.
Deciding spec
The 100 m water-resistance rating is the specification that determines suitability for swimming and snorkelling rather than casual splash protection alone. A rotating bezel adds elapsed-time tracking for underwater timing or general interval use.
Capacity and limits
The 13.40 mm case thickness and Hardlex crystal provide robust everyday durability while the automatic movement delivers a typical 40-hour power reserve when fully wound. The 42.50 mm diameter wears large on slender wrists, and the fixed lug-to-lug span may limit comfort for smaller arm circumferences.

Questions about this item
How does the 42.5 mm case diameter feel on a typical wrist?
The 42.5 mm diameter sits flush on most medium to large wrists without overhang, while the 13.40 mm thickness keeps the profile low enough to slide under a shirt cuff.
What does 100 m water resistance allow in daily use?
The 100 m rating covers swimming, snorkelling and surface water sports, but it is not rated for scuba diving or high-velocity water impact.
Will the 42.5 mm case and stainless steel bracelet fit my wrist without extra links?
The case measures 42.5 mm across and the stainless steel bracelet uses a deployment clasp with micro-adjustment, so most wrists can be sized without adding or removing full links.
