"Blackout" Diver Style • 4R36 Automatic • 42.5 mm

Overview

The Seiko 5 Sports SBSA025, nicknamed the "Blackout," is the stealthiest member of the Seiko 5 Sports Street Style collection. A fully black-coated case, black bezel, and flat black dial with subtle grey printing give it a murdered-out tool-watch look that pairs with anything. It's built on Seiko's classic dive-watch case shape and powered by the in-house Cal. 4R36 automatic, with hand-winding, hacking seconds, and a day-date display, all visible through the exhibition case back. A rotating bezel and 100 m water resistance round out a capable everyday automatic. This example is brand new in box with its original papers and tags.
