Vintage Seiko Chronograph 6139-7002 manufactured August 1975. Japan made, featuring a unique oval case design, a column wheel chronograph mechanism, day-date complication, and quick-set date feature, Seiko bracelet and clasp, and Seiko's famous 6139 automatic movement.
Part of Seiko's groundbreaking 6139 series—one of the world's first automatic chronographs—this particular reference showcases a striking black dial with white tachymeter scale.
