I have two of the same in my collection and that’s why I’m selling this one.
This helmet is in perfect working and aesthetic condition. All macro images show watch from all angles on them you see even the smallest details that you cannot see with the naked eye. Watch working and keep time perfect, chronograph reset to zero without error, pushers working smooth, fast day/date set by press crown working smooth, fishbone bracelet have full size, mineral glass is without any scratches. Watch is without any hidden flaws, it does not need any additional investment.
This watch serial number is 616037 , produced date is January 1976.
Very hard to find so good Seiko Helmet today, and there are fewer and fewer of them.
