Seiko has announced a trio of new and exciting models. Based on the latest generation of Prospex Speedtimer Chronographs, these new models embody the spirit of the original model from 1969, albeit offered with the latest technologies that the new Prospex Speedtimer Chronograph models now have. The three new models are all spirited timepieces, depicting the collection’s core design ethos all the while providing points of distinction and differentiation. Each of the three new Prospex Speedtimer Chronographs are powered by Seiko’s Calibre V192. This is a calibre reliant on solar energy, be it from the Sun or an artificial light. When fully charged, the Calibre V192 has a power reserve of an incredible 6-months (without being exposed to light). It features a 60-minute chronograph, a 24-hour sub-dial and a date aperture that sits between 4 and 5 o’clock. In terms of chronometry performance, the Calibre V192 has a claimed accuracy of +/- 15 seconds per month at normal operating temperatures.
