Seiko 5 Sports Men's Automatic Watch SNZG17J1 Black

Automatic Sports SNZG17J1: 42mm, 100m, transparent case back, black dial

Collection

The Seiko SNZG17J1 belongs to the Seiko 5 Sports collection, re-launched in 2019. Compared to the classic Seiko 5, the new generation incorporates the 7S36 calibre with hacking (stop-seconds) and manual winding, an exhibition case back, 100m water resistance, and an interchangeable strap system. The case measures 42mm.

Case

The case of the Seiko SNZG17J1 is made of stainless steel, with a diameter of 42 mm and a thickness of 12 mm. The bezel is fixed. The black dial is protected by a Hardlex crystal, Seiko's proprietary treatment for light scratches. The case back is exhibition (transparent), allowing the movement to be observed in operation. Water resistance is 100 m, sufficient for swimming and snorkeling. The indexes and hands are coated with LumiBrite, Seiko's luminescent material for extended night-time readability.

Movement

The Seiko SNZG17J1 is powered by the automatic calibre 7S36, offering a power reserve of approximately 41 hours. This movement does not have hacking (stop-seconds for setting the time) or manual winding — two functions intentionally absent on this entry-level calibre. Its accuracy fluctuates around ±15 seconds per day, which is expected for an automatic movement in this segment. The day-date display is positioned at 3 o'clock.

Bracelet

The Seiko SNZG17J1 is equipped with a stainless steel bracelet, both robust and easy to maintain, fastened by a deployant clasp, which makes it easy to put on and take off the watch while securing the bracelet to the wrist. The lug width is 22 mm.

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