Seiko 5 Men's Automatic Watch SNKG50J1 Gold Black

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

Collection

The Seiko SNKG50J1 belongs to the Seiko 5 range, one of the most iconic lines in Japanese watchmaking. Launched in 1963, this collection embodies accessible automatics: a 37mm case, 21-jewel 7S26 caliber, and 30m water resistance. Note: the 7S26 does not feature hacking or manual winding—an intentional characteristic of this entry-level caliber.

Case

The case of the Seiko SNKG50J1 is made of stainless steel, with a diameter of 37mm and a thickness of 11mm. The bezel is fixed. The Black dial is protected by a 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 SNKG50J1 is powered by the automatic caliber 7S26, offering a power reserve of approximately 41 hours. This movement does not feature hacking (stopping the second hand for time setting) or manual winding—two functions intentionally absent from this entry-level caliber. Its accuracy oscillates around ±15 seconds per day, which is expected for an automatic movement in this segment.

Strap

The Seiko SNKG50J1 is equipped with a stainless steel bracelet, both robust and easy to maintain, secured by a folding clasp, which makes it easy to put on and take off the watch by securing the strap to the wrist. The lug width is 18mm.

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