Part of Seiko’s Core series, this analog watch features a deep-set dial with a 60-minute chronograph that offers a split-seconds feature, which provides the ability to time two events at once. The running seconds subdial is at 6 o’clock and the 60-minute chronograph timer subdial is at 12 o’clock. When the latter complication reaches 60 minutes, it starts again from zero and will continue on this pattern for 12 hours.
