This isn't just a looker; it's a genuine Japanese Domestic Market icon that helped build Seiko's reputation for serious mechanical prowess.

What makes this watch a true collector's piece is its flyback chronograph function, a high-end complication that lets you instantly reset and restart the timer with a single push.
