Seiko 5 Sports Automatic Men's Watch SRPE51K1 Black Grey

Seiko 5 Sports Black 42.5mm: 4R36 with Hacking, 22mm Lug Width

Collection

The Seiko SRPE51K1 belongs to the Seiko 5 Sports collection, re-launched in 2019. Compared to the classic Seiko 5, the new generation features the 4R36 caliber with hacking (stop-seconds) and manual winding, an exhibition case back, 100m water resistance, and an interchangeable strap system. The case measures 42.5 mm.

Case

The case of the Seiko SRPE51K1 is made of stainless steel, with a diameter of 42.5 mm and a thickness of 13 mm. The bezel is fixed. The black dial is protected by Hardlex glass, Seiko's proprietary treatment for minor 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 hour markers and hands are coated with LumiBrite, Seiko's luminescent material for extended nighttime readability.

Movement

The Seiko SRPE51K1 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.

Bracelet

The Seiko SRPE51K1 is equipped with a stainless steel bracelet, both robust and easy to maintain, fastened by a folding clasp, which makes putting on and taking off the watch easier while securing the bracelet to the wrist. The lug width is 22 mm.

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