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 ‘Circuit Race’ Speedtimer is inspired by vintage circuit racing – when cars would rally with extraordinary speed and excitement.
Encased in a black aluminium bezel with gold-coloured plating and a sapphire crystal glass, this chronograph features a black 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.
