This is a fantastic piece of 1970s Japanese racing history- powered by the highly innovative Seiko Caliber 7017, an integrated automatic chronograph movement. The 7017 is technically fascinating because it includes a true Flyback function- meaning the chronograph can be instantly reset and restarted with a single push of a button- a feature usually reserved for much more expensive high-end chronographs. The movement also features a Column Wheel and the coveted Vertical Clutch system, guaranteeing smooth, precise operation and a precise hand start without the usual shudder.
The large- Cushion-shaped case is pure 1970s style, giving the watch a substantial and aggressive wrist presence. The inner bezel includes a useful Pulsometer scale, allowing the wearer to calculate a pulse rate over 30 beats- a specific detail that enhances its tool-watch appeal. This watch is a technical marvel and a true piece of racing history!
