SPB515J1
The Seiko Prospex SPB515J1 Speedtimer Automatic Men Watch pays tribute to Seiko’s legendary 1969 Speedtimer, a milestone in chronograph innovation. This updated design is the first Speedtimer powered by the in-house 6R55 automatic calibre, offering a 72-hour power reserve and the slimmest 6R case at just 11.95mm. Its 39.5mm stainless steel case, inspired by the 1972 Seiko “Panda,” features a curved sapphire crystal and a rotating inner countdown timer ring. With strong Lumibrite for day and night clarity and 200-meter water resistance, this Speedtimer blends heritage design with modern precision and durability.
