SPB513J1
The Seiko Prospex SPB513J1 Speedtimer Automatic Men Watch reimagines the groundbreaking 1969 Speedtimer with refined modern upgrades. Powered by the in-house 6R55 automatic calibre, it offers a robust 72-hour power reserve and is the slimmest 6R model ever at just 11.95mm. Its 39.5mm stainless steel case, inspired by the 1972 Seiko “Panda,” is topped with curved sapphire glass, showcasing a silver-white dial encircled by a rotating inner countdown timer. Enhanced with Lumibrite for day and night clarity, screw case back, and 200-meter water resistance, this Speedtimer combines heritage aesthetics with precision engineering.
