Seiko 5 Sports 40mm Mens Watch Black

Ref. SRPE57K1

A clean, bezel-less case in brushed and polished stainless steel measures 40mm across and 11.5mm thick, with a lug-to-lug span of 44.6mm and 20mm lug width. The matte black dial carries applied gold-coloured hour markers and matching hands, both heavily coated in LumiBrite for low-light legibility. A day-date display sits at three o'clock, and the crown is positioned at four to sit more comfortably against the wrist. The 4R36 automatic calibre runs at 21,600vph with a 41-hour power reserve, hacking seconds, and manual winding. A Hardlex crystal protects the dial; a see-through exhibition caseback shows the movement. The three-row oyster-style bracelet fastens with a three-fold push-button clasp.
