This very nice Seiko chronograph is from 1974. It has the very sophisticated 6138 movement featuring a three register chronograph and differs from most Swiss chronographs in that it doesn’t have a dedicated second hand. But then most Swiss chronos where not automatic wind, didn’t have a date let alone day display and they cost a lot more.
This watch has been beautifully restored (not by me) and I think that it is all original, including the bracelet.
It is signed 4 times and the square sub dials inside a round dial is unusual but looks great.
