145th Anniversary Limited Edition Prospex Speedtimer Mechanical Chronograph Watch SRQ059J1

This limited edition timepiece is one of a small collection to commemorate the 145th Anniversary of the beginnings of Seiko as a Tokyo clock and watch repair shop in 1881. These pieces take design and watchmaking inspiration from moments in Seiko’s history, bringing them up to date for today with the latest technical and design innovations and gold-coloured accents.

The Seiko Speedtimer was a major innovation milestone in 1969 – the world’s first automatic chronograph watch with column wheel and vertical clutch. This 2026 design is inspired by a classic from the archives; the 1972 Seiko 'Panda'. Under dual-curved sapphire glass, the classic silver-white dial features elegant gold-coloured accents for legibility. The dial pattern pays homage to the original Japanese pocket watches of the 1890s, when Seiko moved from repairing clocks and watches to creating them.

Powered by the in-house built 8R48 mechanical chronograph calibre, this movement allows accurate measurement of elapsed time by combining a vertical clutch and a column wheel in a 49.5mm lug to lug, 42mm diameter case size. It has a smooth flowing case and elegant multi-row bracelet to ensure a comfortable fit.

The 8R watch movement series has been designed by Seiko for maximum precision with 3 key elements: a vertical clutch that eliminates shuddering or jumping of the hands when the start/stop button is pushed, a column wheel to ensure precise control of chronograph operation and a 3-pointed hammer that returns all hands to zero instantly in perfect synchronisation when the re-set pusher is pressed.

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.
