Seiko Automatic Men's Watch SKX009K1 Blue Red Rubber Strap

Seiko SKX009K1 Diver: 7S26 40 hours, Hardlex crystal, 200m water resistance

Collection

The Seiko SKX009K1 belongs to the legendary Diver's SKX series, produced from 1996 to 2019. ISO 6425 certified, this automatic diving watch established itself as the go-to reference for accessible divers thanks to its robust 7S26 caliber, 42.5 mm case, and 200m water resistance. The cessation of its production in 2019 only heightened its iconic status.

Case

Made of stainless steel, the case of the Seiko SKX009K1 measures 42.5 mm in diameter and 13.25 mm in thickness. The unidirectional rotating bezel allows for precise measurement of dive times. The dial is protected by a Hardlex crystal, a proprietary Seiko treatment for light scratches. The case back is exhibition (transparent), allowing the movement to be observed in operation. The water resistance is 200 m, compliant with ISO 6425 diving standards. The indexes and hands are coated with LumiBrite, Seiko's luminescent for prolonged nocturnal readability.

Movement

The Seiko SKX009K1 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 from 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 SKX009K1, secured by a folding clasp, complements the case with consistency. The lug width is 22 mm.
