Japan-made automatic watch

The Seiko 5 SNKK17J1 is a men's dress watch powered by the 7S26 automatic calibre with 21 jewels. It is built for daily wear and draws energy from wrist motion rather than a battery. The 38.00 mm stainless-steel case suits a range of wrist sizes.

Stainless steel build and deployment clasp

A solid stainless-steel bracelet fastens with a deployment clasp that secures the watch without stressing the spring bars each time. Mineral crystal protects the black dial and its index markers. The integrated bracelet keeps the profile slim under a shirt cuff.

Thirty-metre water resistance

The case is rated to 30 m, which covers splashes and brief immersion but not swimming or showering. The crown is not screw-down, so water can enter if operated while wet. Buyers needing a dive-rated watch or a screw-down crown should consider other models.
