Seiko 5 Men's Automatic Watch SNXB65J5 Silver Gray

Reliability and understated elegance: the Seiko 5 SNXB65J5 in grey, 37mm, 30m

Collection

The Seiko SNXB65J5 belongs to the Seiko 5 series, produced continuously for over six decades. It is one of the few entry-level automatics to rely on an in-house caliber: the 7S26, which is reliable and low-maintenance. It features a 37mm case, 30m water resistance, and an exhibition case back to view the rotor.

Case

Made of stainless steel, the case of the Seiko SNXB65J5 measures 37 mm in diameter and is 11 mm thick. The bezel is fixed. The 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 SNXB65J5 is powered by the automatic caliber 7S26, offering a power reserve of approximately 41 hours. This movement does not feature hacking (stop-seconds 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 SNXB65J5, secured by a folding clasp, complements the case cohesively. The lug width is 18 mm.

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