This Prospex Speedtimer Solar Chronograph Watch is a precision chronograph that’s inspired by the very first chronographs Seiko® developed for international sporting events in the 1960s. Powered by solar energy, this watch will never need a battery replacement, and it has a power reserve that lasts approximately six months. Able to measure up to 60 minutes of elapsed time in 1/5-second increments with a split time function, this chronograph is purpose-built for the sporting man. It features a white dial with sand-blasted texture and black subdials for a classically handsome look, a black tachymeter bezel, LumiBrite hands and markers for visibility at night and a curved sapphire crystal for superior scratch resistance. The case and bracelet are made of durable stainless steel. Secure the watch to your wrist with a tri-fold push button release clasp. Water-resistant to 100 meters.
