Seiko Prospex ‘Grand Touring’ Solar Speedtimer Chronograph SSC939P1
Product Description
Introduced in 1969, the Seiko Speedtimer was a major milestone in chronograph innovation, and marked the beginning of an important decade of the Speedtimer in its prime. The 70s were famed for many things: fashion, music, but also motorsports. Designed under the theme of ‘Classic Motorsports,’ the ‘Grand Touring’ Speedtimer is inspired by, and designed to be reminiscent of, vintage muscle cars that would race down endless highways.
Encased in a navy-blue aluminium bezel and sapphire crystal glass, this chronograph features a clean-cut grey dial, with hour and minute hands that resemble the original Speedtimer from 1969. With 12 spots of Lumibrite, this timepiece is designed to be legible in darker conditions. With a chronograph second scale around the dial ring, this piece also features a Tachymeter on the bezel for measuring speed – an iconic element of the original Seiko Speedtimer.
Featuring a solar-powered V192, this Speedtimer chronograph is accurate to +/- 15 seconds per month, whilst maintaining a full charge of 6 months.
Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
