Mint and unworn looking condition Seiko Porspex Speedtimer model reference SRQ039. It comes complete with box and papers purchased in June 2022 and it's on lightly worn original blue leather strap. The UK retail price is £2730. It is a Japan made model, built to the hugest of specifications. The Speedtimer chronograph takes inspiration from the 1969 Speedtimer, an important landmark in the history of chronograph watchmaking. Applying the technology invented for Seiko's stopwatches, the 1969 Speedtimer was the world's first automatic chronograph with a column wheel and vertical clutch. These two devices made the measurement of elapsed time more precise and error-free than ever before. The new model is to be the signature of the Speedtimer series. It inherits the innovative technology of the original model while achieving further evolution as a time measuring instrument.

This watch uses the Seiko Calibre 8R Series, designed for maximum precision in every aspect. This calibre is designed and hand assembled completely in-house by Seiko's most skilled watchmakers. All watches are powered by the calibre 8R series, the brand’s most advanced automatic chronograph movement for mechanical watches. This calibre incorporates both vertical clutch and column wheel mechanisms which ensure the precision and durability. The escapement is lightweight and strong, thanks to the use of MEMS technology which enhances the stability of the watch's precision.
