Seiko made its first watch in 1913, and 50 years later, Seiko 5 was born in 1963. In its long history, Seiko 5 has won respect, affection, and loyalty of young people from all around the world. Seiko 5 Sports offers a new opportunity to feel the spirit of the active and innovative design of that time. Seiko set out to build a watch with five attributes, from which the watch gets its name: a self-winding automatic movement, resistance to water, a day-date in a single window, a recessed crown, and a durable case.

4R36 automatic caliber

Some people fell in love of taking a brand new, modern watch and customizing it with their twist, whereby the means of colored coatings (often blacked-out), different dial configurations, or elaborate engravings. And this phenomenon has become a rising trend in the watch industry.



The Seiko 5 Sports “Street Style” Blackout Automatic Ref. SBSA025 took this all-black approach, we mean literally, for the first time since its Skx days. It features an open back and now powered by Seiko's automatic caliber, 4R36, operating at 21,600 BPH (3 Hertz) with hacking and hand winding capabilities. It has 24 jewels with a power reserve of 40 hours. This is a major upgrade from the previous 7S26 non-hacking and winding caliber that used for the old SKX007J1. You know what, since this JDM model features the day/date display, one can self-select the day display to Japanese kanji characters, or in English.



The Seiko 5 Sports “Street Style” Black still holds a 100m water resistant stainless steel case done in full matte-tone black, measuring at 42mm wide without the crown, a lug to lug length of only 46mm, and a height of about 13mm, with a lug width of 22mm. The whole dimension and case design are true to its predecessor, thus moreover the short lugs to lugs length mean this watch wraps around the wrist on all(small or big) wrist sizes like a glove making it extremely comfortable.



Full blackout case and dial



The bezel is aluminum and has large blackout printed markings on it. It rotates buttery smooth into 120 positions has little to no free play in anti-clockwise direction. Sitting atop of the bezel is Seiko’s Hardlex. The whole matte finishing throughout the whole watch gives it a tool watch touch with much added sleekness to it.



The matte black dial gets some makeover while still utilitarian. Like for instant, the new Seiko 5 logo has the “5” tilted 45 degrees anti-clockwise. The Logo is then balanced off symmetrically with the bottom Seiko’s Sumo “Automatic” font style instead of the old orange “diver’s 200m” text. The large and SKX’s heirloom indices stay home and make reading easy as it always done so, so are the classic Seiko hour and minutes hands. The hour markers are now surrounded with metal trims, and hands are finished in matte black also (as we said, its literally black all out). Both the markers and handset though done black, Seiko had them generously coated with Seiko's LumiBrite allowing it to glow brightly in the dark for hours.



The Seiko 5 Sports “Street Style” Blackout Ref. SBSA025 comes with on a nylon nato strap with matte black buckle to fit the whole street cool theme.
