The new SSC913P1 model joins the Prospex Speedtimer collection. As with all Speedtimer chronographs, every detail is designed to reflect the precision required for elapsed time measurement at the highest level. The chronograph second hand extends to the tachymeter markings on the edge of the dial. The minute hand at six o'clock and the central second hand are both red, so that the elapsed time can be accurately read at a glance. The date display is placed between the markers so that the time is always clearly visible. The timepiece is powered by Seiko's solar-powered calibre V192, which offers a 60-minute chronograph, a 24-hour sub-dial and, when fully charged, operates for up to six months without exposure to light. The smooth finish of the strap combined with the domed sapphire glass crystal gives the watches a classic yet sporty look.
