Seiko Solar Alarm Chronograph SSC501 SSC501P1 SSC501P Men’s Watch

SEIKO were early pioneers in solar watches, beginning in 1977 and before the green movement grew strong. This is what a maintenance free watch should be; eco-friendly and hardy enough to handle just more than taps. It does not require purely sunlight; just any light will do. Runs more or less six months on a full charge, in complete darkness. One minute of sunlight is equal to three minutes of artificial, considerably-bright light for this watch.
