Since 2013, Seiko's Space Link GPS clock has been the first clock for home or office use that receives a time signal from nearby GPS satellites, giving accuracy of around a second every 100,000 years. The clocks can still receive the time signal even indoors, up to 15 metres from the open sky. The clock updates 4 times a day, and retains normal timekeeping using a high accuracy quartz movement outside this adjustment time. This clock is the 33cm model, with brown marbled case, and white dial with stark black numerals and hands.
