For sale is the Seiko Prospex Speedtimer SRQ037J1, a premium automatic chronograph inspired by Seiko’s historic 1964 stopwatch and early Speedtimer heritage. This model combines vintage motorsport styling with modern mechanical chronograph engineering and was released as a limited edition of 1,000 pieces worldwide.
The watch features a 42.5mm stainless steel case with super-hard coating, paired with a dual-curved sapphire crystal and anti-reflective coating for excellent clarity and durability. Its charcoal/black dial design pays tribute to Seiko’s original timing instruments, with highly legible sub-dials, tachymeter scale, and classic chronograph styling.
Powered by Seiko’s high-end automatic Calibre 8R46 chronograph movement, the SRQ037J1 uses a column wheel and vertical clutch system, technology typically found in far more expensive Swiss chronographs. It offers smooth chronograph operation, excellent reliability, and approximately 45 hours of power reserve.
Finished on a solid stainless steel bracelet with push-button clasp and featuring a see-through caseback, this Speedtimer delivers both strong everyday wearability and serious collector appeal.
