Seiko 5 Automatic SNKL23K1 38 mm Black Dial Automatic Watch

Dress watch with automatic movement

The Seiko 5 SNKL23K1 is a 38 mm stainless steel dress watch driven by the 7S26 automatic calibre with 21 jewels. A black dial carries luminous silver-tone hands and index markers plus a day-date window at 3 o'clock. Hardlex crystal and a fixed bezel protect the face, while a deployment clasp secures the matching bracelet.

Suits daily wearers who want mechanical simplicity

Buyers who need higher water resistance for swimming or diving should look elsewhere. The 30 m rating only covers splashes and brief immersion. Anyone requiring a sapphire crystal or a hacking movement will not find those features here. The 10.5 mm case thickness sits close to the wrist but adds no extra functionality.

7S26 calibre with 40-hour reserve

The movement runs at 21600 vph and stores roughly 40 hours of power when fully wound. It has 21 jewels and is based on the 7002 architecture. No manual-wind or hacking function is present, so the watch relies on regular wrist motion to keep running.
