Seiko 5 Sports Men's Automatic Watch SRPK17K1 55th Anniversary Limited Edition

55th Anniversary Seiko 5 Sports: SRPK17K1, Automatic 4R36, 42.5 mm, 100 m

Collection

The Seiko SRPK17K1 belongs to the Seiko 5 Sports collection, revamped in 2019. Compared to the classic Seiko 5, the new generation incorporates the 4R36 caliber with hacking (stop-seconds) and manual winding, an exhibition case back, 100 m water resistance, and an interchangeable strap system. The case measures 42.5 mm.

Case

The case of the Seiko SRPK17K1 is made of stainless steel, with a diameter of 42.5 mm and a thickness of 13 mm. The unidirectional rotating bezel allows for precise measurement of dive times. The black dial is protected by Hardlex glass, a proprietary Seiko treatment for light scratches. The case back is exhibition (transparent), allowing observation of the movement 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 nighttime legibility.

Movement

The Seiko SRPK17K1 is powered by the automatic caliber 4R36, offering a power reserve of approximately 41 hours. It includes hacking (stop-seconds 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.

Strap

The Seiko SRPK17K1 is equipped with a stainless steel bracelet, both robust and easy to maintain, closed by a folding clasp, which facilitates putting on and taking off the watch by securing the bracelet to the wrist. The lug width is 22 mm.

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