Seiko Prospex Speedtimer Automatic DATSUN Limited Edition SPB517J1

Seiko Speedtimer Automatic DATSUN Limited Edition – Two Legends. One Shared Race Track.

1969 – a year when Japanese engineering made sports history. DATSUN introduced its first sports car, the 240Z, and Seiko unveiled the revolutionary Speedtimer. Both became icons – one on the road, the other on the wrist. At the legendary East African Safari Rally 1971, the Seiko logo adorned the winning DATSUN model – a symbol of precision, performance, and endurance.

Today, this story returns with the Seiko Speedtimer Automatic DATSUN Limited Edition, limited to only 2,500 pieces worldwide.

Design with Motorsport Soul

The matte dial of the SPB517J1 recalls the instruments of a rally cockpit – minimalistic, functional, and full of dynamism. Red accents on the seconds hand and inner bezel set the pace, while the DATSUN logo at 6 o’clock unmistakably highlights the historic connection. The crown at 4 o’clock operates the rotating inner ring as a countdown timer – a tool that impresses visually and works at racing speed.

Built for Performance

The hard-coated stainless steel case with a diameter of 39.5 mm sits compactly on the wrist, while the curved, anti-reflective sapphire crystal ensures perfect visibility. 20 bar water resistance, a power reserve of more than 72 hours, and the robust Caliber 6R55 make the watch a reliable partner – whether on the race track, country road, or everyday life. The sustainably made leather strap with folding clasp offers high wearing comfort and secure fit.
