Product Identity
The Seiko SNK809K1 is a 36mm automatic wristwatch with a black dial and stainless steel construction. It suits adults who prefer a compact dress watch for daily wear or formal occasions.
Sustained Operation
The automatic movement runs continuously from wrist motion without a battery. Water resistance to 30 meters protects against splashes and brief immersion but not swimming or diving.
Interface Limits
The 18mm lug width determines which replacement straps will fit. The deployment clasp secures the included stainless steel bracelet, which adjusts to an 8 inch band length.

Questions about this item
Does the automatic movement make any audible ticking or generate heat during all-day wear?
The mechanical movement runs silently on wrist motion and produces no noticeable heat.
What strap tool is needed to adjust the 18 mm stainless steel bracelet?
A standard spring-bar tool lets you add or remove links on the 18 mm band.
Will the 30 m water resistance survive hand-washing if I keep wearing my older leather-strap watches in rotation?
The 30 m rating covers splashes and brief immersion, so normal hand-washing is fine while you rotate other watches.
