Seiko 5 Men's Automatic Watch SNKK11K1 Blue

Classic Blue Seiko 5: 7S26 21 Jewels, 37mm, Exhibition Case Back

Collection

The Seiko SNKK11K1 belongs to the Seiko 5 series, which has been in continuous production for over six decades. It is one of the few entry-level automatics to rely on an in-house caliber: the reliable and low-maintenance 7S26. 37mm case, 30m water resistance, exhibition case back to observe the rotor.

Case

Made of stainless steel, the case of the Seiko SNKK11K1 measures 37mm in diameter and 11mm in thickness. The bezel is fixed. The dial is protected by Hardlex crystal, a proprietary Seiko treatment for light scratches. The case back is exhibition (transparent), allowing observation of the movement in operation. The water resistance is 30m, suitable for splashes and rain.

Movement

The Seiko SNKK11K1 is powered by the automatic caliber 7S26, offering an approximate power reserve of 41 hours. This movement does not feature hacking (stopping the second hand for time setting) or manual winding — two functions intentionally absent on this entry-level caliber. Its accuracy hovers around ±15 seconds per day, which is expected for an automatic movement in this segment.

Bracelet

The stainless steel bracelet of the Seiko SNKK11K1, closed by a deployant clasp, complements the case coherently. The lug width is 18mm.

Supplied with: Storage box, presentation pad, user manual.
