Four new solar chronographs inspired by the 1969 Speedtimer complete the new series. Powered by Caliber V192, they offer a 24-hour indicator, a time of day seconds hand, a 60-minute chronograph in a sub-dial at six o’clock and a power reserve function. They are offered in four different dial colors; white, navy, gold and black and will join the main Prospex collection. The case shape is faithful to the original but its 39mm diameter, the combination of hairline and smooth polishing on the bracelet and the curved sapphire glass bring it right up to date.
