Seiko 5 Sports Men's Automatic Watch SRPK99K1 Black Gold

The 5 Sports Black: 42.5 mm case, 4R36 hacking & manual winding caliber

Collection

The Seiko SRPK99K1 belongs to the Seiko 5 Sports range. This sporty and accessible collection offers a reliable 4R36 automatic movement in a 42.5 mm steel case, water-resistant to 100 m — sufficient for swimming and active daily life. The black dial and unidirectional bezel provide optimal readability.

Case

Made of stainless steel, the case of the Seiko SRPK99K1 measures 42.5 mm in diameter and 13 mm in thickness. The unidirectional rotating bezel allows for precise dive time measurement. 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 100 m, sufficient for swimming and snorkeling. The indexes and hands are coated with LumiBrite, Seiko's luminescent material for extended nighttime readability.

Movement

The Seiko SRPK99K1 is powered by the automatic caliber 4R36, offering a power reserve of approximately 41 hours. It includes hacking (stop-second function for precise time setting) and manual winding, two conveniences absent on the previous generation 7S26 caliber. The day-date display is positioned at 3 o'clock.

Bracelet

The stainless steel bracelet of the Seiko SRPK99K1, secured by a folding clasp, complements the case coherently. The lug width is 22 mm.
