Seiko Prospex Speedtimer Automatic SPB513J1 - NEW

The SPB513J1 marks the entry of the Speedtimer line into the world of mechanical three-hand watches. Inspired by the legendary 1972 Seiko Speedtimer – the iconic "Panda" model – this watch combines sporty functionality with clear Seiko tradition. The result is an automatic tool watch that remains deliberately minimalist, yet still offers high utility.

A key feature is the internal, rotating countdown ring , operated via the crown. It allows for flexible timekeeping in everyday life or during sports – for example, for start times, breaks, or stages. A LumiBrite -coated ▼ marker ensures that the set reference time remains clearly legible even in low light conditions. The high-contrast white and black dial adopts the classic panda color scheme and gives the watch its distinctive character.

Inside, the modern 6R55 automatic movement operates with a power reserve of up to 72 hours . This makes the SPB513J1 not only sporty, but also suitable for everyday use and reliable. The flowing case design, the domed sapphire crystal, and the solid stainless steel bracelet underscore the robust character of this Prospex Speedtimer – made for people who appreciate function and want to wear history.
